Lookup float/double constants from exec_env->native_symbol table
but not construct them with LLVMBuildConst if XIP mode is enabled,
these constants are introduced by f32/f64.const opcodes and some
float/double conversion opcodes, and make wamrc generate some
relocations in text section of AOT XIP file. This patch eliminates such
relocations when "--enable-indirect-mode" is added to wamrc.
Use the previous resolved binary type info (obj_data->target_info.bin_type) to
check the endian and bit-width but not the raw binary info, the latter is not
suitable for the check for Win32 object file type.
And fix the symbol comparison issue in resolve_target_sym(), as in Win32, the
symbol name of a function added by LLVMAddFunction() is prefixed by '_',
which leads to invalid result returned by strcmp().
Refine some codes in wasm loader
Add -Wshadow to gcc compile flags and fix some variable shadowed issues
Fix function parameter/return types not checked issue

Treat R_AARCH64_JUMP26 same as R_AARCH64_CALL26, both of their

(BL) instructions, the other is for jump (B) instructions.
Auto detect whether file is XIP file before loading module in posix like and
linux-sgx platforms, and if yes, mmap executable memory automatically to
run the XIP file.
Add document about XIP feature.
Enable test spec cases with XIP feature.
When auxiliary stack global isn't found in wasm app, it must be unused in
the wasm app, we set it to __heap_base global and set its size to 0, so as to
shrink the linear memory to reduce the memory consumption.
Fix some potential pointer overflows in aot applying relocations and
several other places.
And add sanitizer compiler flags to wamrc CMakeLists.txt to detect
such issues.
Enable LLVM link time optimization for AOT and enable it by default,
and provide "wamrc --disable-llvm-lto" option to disable it.
And modify the spec test script, disable it by default when testing
spec cases.

Currently the string in the wasm/aot file will be duplicated and stored
into const string list/set in interpreter/aot loader, which leads to extra
unnecessary memory consumption if the file buffer can be referred to
after loading. We refine the string storage by:
- if the file buffer can be referred to after loading and it is writable, we
reuse the file buffer to store the string but not store it into the const
string set: move string backward and append '\0'
- emit string with '\0' only for XIP mode in which the AOT file is readonly
- if the file buffer cannot be referred to, e.g. in app manager, keep the
same behavior as before

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

Implement XIP (Execution In Place) feature for AOT mode to enable running the AOT code inside AOT file directly, without memory mapping the executable memory for AOT code and applying relocations for text section. Developer can use wamrc with "--enable-indirect-mode --disable-llvm-intrinsics" flags to generate the AOT file and run iwasm with "--xip" flag. Known issues: there might still be some relocations in the text section which access the ".rodata" like sections.
And also enable ARC target support for both interpreter mode and AOT mode.
