Rui Ueyama 1e52f25d46 Add -m elf32_x86_64.
Patch by H.J. Lu.

This patch adds -m elf32_x86_64 to lld. But it doesn't generate working
x32 binaries.

Patch by H.J. Lu.

As x86-64 psABI supports both LP64 and ILP32, this patch adds <ELFT>
template to X86_64TargetInfo.

Justin Lebar e71c08f84c [CUDA] Use the multi-element remove function in EraseUnwantedCUDAMatches.
Summary:
Bug pointed out by Benjamin Kramer in r264008.  I think the bug is
benign because by the time this is called, we should only have at most
two overloads to consider (either a host and a device overload, or a
host+device overload, but not all three).

Justin Lebar 4c2c6fd1c4 [CUDA] Add additional testcases for EraseUnwantedCUDAMatches.
Summary:
Specifically, this patch adds testcases for all three calls to
EraseUnwantedCUDAMatches.  The addr-of-overloaded-fn test I accidentally
neutered in r264207, which moved much of
CodeGenCUDA/function-overload.cu into SemaCUDA/function-overload.cu.
The coverage from overloaded-delete test is new.

Justin Lebar d35f706cc2 [CUDA] Don't assume that destructors can't be overloaded.
Summary:
You can overload a destructor in CUDA, and SemaOverload needs to be
tweaked not to crash when it sees an explicit call to an overloaded
destructor.

Tim Northover 72eebfa4b0 GlobalISel: freeze reserved regs after IRTranslator.

Michael Kuperstein a99c46cc73 [LV] Remove wrong assumption about LCSSA
The LCSSA pass itself will not generate several redundant PHI nodes in a single
exit block. However, such redundant PHI nodes don't violate LCSSA form, and may
be introduced by passes that preserve LCSSA, and/or preserved by the LCSSA pass
itself. So, assuming a single PHI node per exit block is not safe.

Matthias Braun aeab09fb8f BranchFolding: Use LivePhysReg to update live in lists.
Use LivePhysRegs with a backwards walking algorithm to update live in
lists, this way the results do not depend on the presence of kill flags
anymore.

This patch also reduces the number of registers added as live-in.
Previously all pristine registers as well as all sub registers of a
super register were added resulting in unnecessarily large live in
lists. This fixed https://llvm.org/PR25263.
