This is consistent with -Wbuiltin-macro-redefined, and puts this common
extension warning under a flag.

Seems getSomething() is more common naming scheme than just a noun
to get something, so renaming these members.

Atoms with deadStripNever attribute has already been added to the
dead strip root set at end of Resolver::doDefinedAtom, so no need
to check it for each atom again.

Removes unnecessary casts from non-generic address spaces to the generic address
space for certain code patterns.

ELFLinkingContext has a method addUndefinedAtomsFromSharedLibrary().
The method is being used to skip a shared library within --start-group
and --end-group if it's not the first iteration of the group.
We have the same, incomplete mechanism to skip a shared library within
a group too. That's implemented in ELFFileNode. It's intended to not
return a shared library on the second or further iterations in the
first place. This mechanism is preferred over
addUndefinedAtomsFromSharedLibrary because the policy is implemented
in Input Graph -- that's what Input Graph is for.
This patch removes the dupluicate feature and fixes ELFFileNode.

When rematerializing through truncates, the coalescer may produce instructions
with dead defs, but live implicit-defs of subregs:
E.g.
%X1<def,dead> = MOVi64imm 2, %W1<imp-def>; %X1:GPR64, %W1:GPR32
These instructions are live, and their definitions should not be rewritten.

"x.empty()" is more idiomatic than "x.size() == 0". This patch is to
add such method and use it in LLD.

Reversed the order in which LD_LIBRARY_PATH is defined in order to make sure the
${CLOOG_INSTALL} prefix is found first.

By ignoring this pragma with a warning, we're essentially miscompiling
the user's program. WebKit / Blink use this pragma to disable dynamic
initialization and finalization of some static data, and running the
dtors crashes the program.
Error out for now, so that /fallback compiles the TU correctly with
MSVC. This pragma should be implemented some time this month, and we
can remove this hack.

Seems clang-modernize couldn't add "override" to nested classes, so
doing it by hand. Also removed unused virtual member function that
is not overriding anything, that seems to have been added by mistake.

these is very much off and is more than just the branch
from this bug incorrect:

Extend the SSE2 comment lexing to AVX2. Only 16byte align when not on AVX2.
This provides some 3% speedup when preprocessing gcc.c as a single file.
The patch is wrong, it always uses SSE2, and when I fix that there's no speedup
at all. I am not sure where the 3% came from previously.
--Thi lie, and those below, will be ignored--

More updating of tests to be explicit about the target triple rather than
relying on the default target triple supporting ARM mode.
Indicate to lit that object emission is not yet available for Windows on ARM.
