It relies on flutter copy of clang distribution, same one that is used to build flutter/engine.
It addressed several deprecated warnings from clang compiler for functions like strdup, unlink, etc.
It allows few warnings still since they are triggered in third_party sources.

If lookup succeeds, then the DWARF stack frame uses the symbol
name and offset instead of the dynamic library name. The
native_stack_traces package (once updated) can translate these
stack frames into symbolic stack frames even if given a partial
stack trace without the header.
Also, consistently use uword instead of a mix of uintptr_t and uword.

Gardening.
This reverts commit ca20aab384.
That commit causes generation of incorrect register names on
vm-noopt-simarm64-mac-be, and it seems to cause a disk full
error later on (making the bot purple).

Emit CFI information to teach gdb how to unwind Dart frames. Fixes unwinding for Mac x64 and Linux x64/ARM/ARM64. Unwinding already worked for iOS ARM64. Fixes unwinding on Android 6+ ARM.
Emit DWARF information about function inlining and line number mappings. Works with gdb, addr2line and llvm-symbolizer.
With --dwarf-stack-traces, also remove CodeSourceMaps from snapshots and change stack traces to a non-compliant form resembling Android's debuggerd output, which can be passed to ndk-stack.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.
