Currently, ARMBaseInstrInfo::getInstSizeInBytes() uses hard-coded
instruction size for some pseudo-instructions, while this
information should ideally be found in ARMInstrInfo.td,
ARMInstrThumb(2).td files (which can be accessed via MCInstrDesc). Hence,
the .td files should be updated and no hard-coded instruction sizes
should be used by getInstSizeInBytes() anymore.

With these changes, check-asan passes on Linux and Windows.
There are a couple libraries we need to add support for, asan_static, asan_preinit, and the shared library version of asan proper.
Since we need to build the asan proper sources twice, once with -DASAN_DYNAMIC and once without, those sources are no longer in a source_set.
Much of the check-asan target is taken from the existing check-hwasan target.

crt_code seems to correspond to SANITIZER_COMMON_CFLAGS which contains -fno-builtin.

This was done for check-hwasan, but compiler-rt/test/hwasan/lit.cfg.py
already does that.
This makes check-asan (to be submitted) fail on Windows due to using
lld-link (as opposed to MSVC link.exe) in tests. That seems like a
problem that should be fixed, but that's orthogonal to this patch.
D117916 broke some people because some distros are still using a glibc
older than 2.33. Add gn arg llvm_have_mallinfo2 and default to false for
now.

This is in preparation for moving the code that parses and processes
order files into this file.
See https://reviews.llvm.org/D117354 for context and discussion.
I'm seeing deprecated warnings due to using mallinfo() instead of
mallinfo2().
../../llvm/lib/Support/Unix/Process.inc:98:10: warning: 'mallinfo' is deprecated [-Wdeprecated-declarations]
mi = ::mallinfo();
mallinfo2() is part of glibc 2.33 which was released in Feb 2021, which
is fairly recent but I think gn users should be using fairly up to date
glibcs.
If this breaks people we could make this a gn arg instead.
