Implement 2-level Multi-tier JIT engine: tier-up from Fast JIT to LLVM JIT to
get quick cold startup by Fast JIT and better performance by gradually
switching to LLVM JIT when the LLVM JIT functions are compiled by the
backend threads.

Allow to add watchpoints to variables for source debugging. For instance:
`breakpoint set variable var`
will pause WAMR execution when the address at var is written to.
Can also set read/write watchpoints by passing r/w flags. This will pause
execution when the address at var is read:
`watchpoint set variable -w read var`
Add two linked lists for read/write watchpoints. When the debug message
handler receives a watchpoint request, it adds/removes to one/both of these
lists. In the interpreter, when an address is read or stored to, check whether
the address is in these lists. If so, throw a sigtrap and suspend the process.
When a wasm module is duplicated instantiated with wasm_instance_new,
the function import info of the previous instantiation may be overwritten by
the later instantiation, which may cause unexpected behavior.
Store the function import info into the module instance to fix the issue.
Limit max_stack_cell_num/max_csp_num to be no larger than UINT16_MAX,
and don't check all_cell_num in interpreter again.
And refine some codes in interpreter.
Add a new options to control the native stack hw bound check feature:
- Besides the original option `cmake -DWAMR_DISABLE_HW_BOUND_CHECK=1/0`,
add a new option `cmake -DWAMR_DISABLE_STACK_HW_BOUND_CHECK=1/0`
- When the linear memory hw bound check is disabled, the stack hw bound check
will be disabled automatically, no matter what the input option is
- When the linear memory hw bound check is enabled, the stack hw bound check
is enabled/disabled according to the value of input option
- Besides the original option `--bounds-checks=1/0`, add a new option
`--stack-bounds-checks=1/0` for wamrc

Refactor the layout of interpreter and AOT module instance:
- Unify the interp/AOT module instance, use the same WASMModuleInstance/
WASMMemoryInstance/WASMTableInstance data structures for both interpreter
and AOT
- Make the offset of most fields the same in module instance for both interpreter
and AOT, append memory instance structure, global data and table instances to
the end of module instance for interpreter mode (like AOT mode)
- For extra fields in WASM module instance, use WASMModuleInstanceExtra to
create a field `e` for interpreter
- Change the LLVM JIT module instance creating process, LLVM JIT uses the WASM
module and module instance same as interpreter/Fast-JIT mode. So that Fast JIT
and LLVM JIT can access the same data structures, and make it possible to
implement the Multi-tier JIT (tier-up from Fast JIT to LLVM JIT) in the future
- Unify some APIs: merge some APIs for module instance and memory instance's
related operations (only implement one copy)
Note that the AOT ABI is same, the AOT file format, AOT relocation types, how AOT
code accesses the AOT module instance and so on are kept unchanged.

And enable classic interpreter instead fast interpreter when llvm jit is enabled,
so as to fix the issue that llvm jit cannot handle opcode drop_64/select_64.
Normalize wasm types, for the two wasm types, if their parameter types
and result types are the same, we only save one copy, so as to reduce
the footprint and simplify the type comparison in opcode CALL_INDIRECT.
And fix issue in interpreter globals_instantiate, and remove used codes.
Fix dump call stack issue in interpreter introduced by hw bound check:
the call stack isn't dumped if the exception is thrown and caught by
signal handler.
And restore the wasm stack frame to the original status after calling a
wasm function.
Import WAMR Fast JIT which is a lightweight JIT with quick startup, small footprint,
relatively good performance (~40% to ~50% of LLVM JIT) and good portability.
Platforms supported: Linux, MacOS and Linux SGX.
Arch supported: x86-64.
Fix build script to enable hw bound check for interpreter when
AOT is disabled, so as to enable spec cases test for interp with
hw bound check. And fix the issues found.
Implement boundary check with hardware trap for interpreter on
64-bit platforms:
- To improve the performance of interpreter and Fast JIT
- To prepare for multi-tier compilation for the feature
Linux/MacOS/Windows 64-bit are enabled.
Sub module's auxiliary stack boundary and bottom may be different from
main module's counterpart, so when calling sub module, its aux stack info
should be gotten and set to exec_env firstly, or aux stack overflow and out
of bounds memory access exception may be thrown when calling sub
module's function.
Fix the issue reported in PR #1278.
Enable dump call stack to a buffer, use API
`wasm_runtime_get_call_stack_buf_size` to get the required buffer size
and use API
`wasm_runtime_dump_call_stack_to_buf` to dump call stack to a buffer
Refine opcode br_table for classic interpreter as there may be a lot of
leb128 decoding when the br count is big:
1. Use the bytecode itself to store the decoded leb br depths if each
decoded depth can be stored with one byte
2. Create br_table cache to store the decode leb br depths if the decoded
depth cannot be stored with one byte
After the optimization, the class interpreter can access the br depths array
with index, no need to decode the leb128 again.
And fix function record_fast_op() return value unchecked issue in source
debugging feature.
Fix an UBSan complaint introduced by recent change by adding more checks

Enable emitting custom name section to aot file when adding
`--enable-dump-call-stack` or `--enable-dump-call-stack` to
wamrc and there is custom name section in wasm file, which
can be generated by wasi-sdk/emcc "-g" option. So aot runtime
can also get the function name from the custom name section
instead of export section, to which developer should use
`--export-all` for wasi-sdk/emcc to generate export function
names.
Implement source debugging feature for classic interpreter and AOT:
- use `cmake -DWAMR_BUILD_DEBUG_INTERP=1` to enable interpreter debugging
- use `cmake -DWAMR_BUILD_DEBUG_AOT=1` to enable AOT debugging
See doc/source_debugging.md for more details.
Implement wasm_runtime_init_thread_env() for Windows platform by calling os_thread_env_init(): if current thread is created by developer himself but not runtime, developer should call wasm_runtime_init_thread_env() to init the thread environment before calling wasm function, and call wasm_runtime_destroy_thread_env() before thread exits.
And clear compile warnings for Windows platform, fix compile error for AliOS-Things platform

Enable RISCV AOT support, the supported ABIs are LP64 and LP64D for riscv64, ILP32 and ILP32D for riscv32.
For wamrc:
use --target=riscv64/riscv32 to specify the target arch of output AOT file,
use --target-abi=lp64d/lp64/ilp32d/ilp32 to specify the target ABI,
if --target-abi isn't specified, by default lp64d is used for riscv64, and ilp32d is used for riscv32.
