This patch makes changes that are necessary to prevent the compiler from using
the "coal" sections and have it use the non-coal sections instead when the

the weak-def bits.

Also, have the assembler issue a warning if it encounters a *coal* section in
the assembly file and inform the users to use the non-coal sections instead.

Some background on why we don't have to use *coal* sections anymore:
Long ago when C++ was new and "weak" had not been standardized, an attempt was
made in cctools to support C++ inlines that can be coalesced by putting them
into their own section (TEXT/textcoal_nt instead of TEXT/text).

The current macho linker supports the weak-def bit on any symbol to allow it to
be coalesced, but the compiler still puts weak-def functions/data into alternate
section names, which the linker must map back to the base section name.

This patch makes changes that are necessary to prevent the compiler from using
the "coal" sections and have it use the non-coal sections instead when the
target architecture is not powerpc:

TEXT/textcoal_nt instead use TEXT/text
TEXT/const_coal instead use TEXT/const
DATA/datacoal_nt instead use DATA/data

If the target is powerpc, we continue to use the *coal* sections since anyone
targeting powerpc is probably using an old linker that doesn't have support for
the weak-def bits.

Also, have the assembler issue a warning if it encounters a *coal* section in
the assembly file and inform the users to use the non-coal sections instead.

This patch teaches x86 fast-isel how to select nontemporal stores.

Instructions (V)MOVNTPS/PD/DQ can be used for SSE2/AVX aligned nontemporal
vector stores.

Before this patch, fast-isel always selected 'movd/movq' instead of 'movnti'
for doubleword/quadword nontemporal stores. In the case of nontemporal stores
of aligned vectors, fast-isel always selected movaps/movapd/movdqa instead of
movntps/movntpd/movntdq.

With this patch, if we use SSE2/AVX intrinsics for nontemporal stores we now
always get the expected (V)MOVNT instructions.

This makes overriding LLVM_VERSION_* not work properly with newer versions of CMake. To make this work properly we need to:

(1) Optionally set the policy to NEW

(3) If the policy is set, pass the VERSION and LANGUAGES options in the new format

AMDGPU: Remove implicit ilist iterator conversions, NFC

One of the changes in lib/Target/AMDGPU/AMDGPUMCInstLower.cpp was a new
one.  Previously, bundle iterators and single-instruction iterators
could be compared to each other (comparing on underlying pointers).
I changed a comparison from using `MBB->end()` to using
`MBB->instr_end()`, since both end iterators should point at the some
place anyway.

I don't think the implicit conversion between the two iterator types is
a good idea since it's fairly easy to accidentally compare to the wrong
thing (they aren't always end iterators).  Otherwise I would have just
added the conversion.

Even with that, no there should be functionality change here.

The issue with the malformed-machos 00000031.a test is that it needed ‘-arch x86_64’
flag as it was a Mach-O universal file.

The default as to which architecture slice that is dumped without an -arch flag
depends on the host architecture and the contents of the universal file.  The
malformed archive 00000031.a file has both an x86_64 and i386 slice.  So for
for x86_64 hosts only that slice is dumped, for non-x86_64 hosts, which is many
of the bots both slices are dumped.

The test is intended to only check that the malformation of the x86_64 which
has a non-decimal characters in the size field of the archive header so it no
longer crashes.

The problem turned out that the i388 slice of the malformed archive had a
different malformation which was causing the non-x86_64 bots to get this error:

llvm-objdump -macho -disassemble -arch i386 00000031.a

and causing the test as it was written to fail.  So by adding ‘-arch x86_64’ it
should correct the test and the malformation on the i388 slice will not be
dumped.

Also the removal of the malformed-machos mem-crup-0261.macho was not causing
the issue so that is put back in.
