Vyacheslav Egorov d7a57a5df4 [vm] Add feature to connect AOT code to code comments via .debug_line
Option --write_code_comments_as_synthetic_source_to=file tells AOT
compiler to create a file which contains code comments for all code
objects written into an ELF snapshot and then emit a DWARF line number
program into .debug_line section which attributes code to code comments
in a way similar to how our own disassembler does it.

This enables tools like objdump to display our code comments as part of
the disassembly.

This CL also tweaks ifdefs in such a way that IL printer and code comments
facilities is now included into PRODUCT gen_snapshot binary.

TEST=manually run product build with --print-flow-graph and --write_code_comments_as_synthetic_source_to

Vyacheslav Egorov a41a1dc917 [vm/compiler] Split compiler sources out of normal VM sources.
Make them form its own source set (libdart_compiler) and completely exclude
them from AOT runtime targets.

Previously we had some inconsistencies, with some files were using
DART_PRECOMPILED_RUNTIME to fully or partially exclude either contents
from their headers or from implementation, while other files did nothing
and relied on linker to throw their contents away.

This change tries to address this inconsistency.

A follow up change would include a check in most compiler headers which
would prohibit to use them while building AOT runtime.

Samir Jindel bc16959fc7 Reland "[vm/ffi] Dispatch native callbacks through trampolines if we can't ensure callbacks will always be executable."
The original revision is in patchset 1.

Three bugs are fixed:

1. Fix SIMARM_X64 build: no need to generate trampolines for AOT or simulated JIT.
2. Hot-reload: Fix hot-reload: don't invalidate Code for force-optimized functions.
3. Windows: Provide shadow space to runtime routines.
