This modification generates proper copyin/initialization sequences for array variables/parameters. Before they were considered as pointers, not arrays.

Summary:
The documentation writes vectors highest-index first whereas LLVM-IR writes
them lowest-index first. As a result, instructions defined in terms of
left_half() and right_half() had the halves reversed.
In addition to correcting them, they have been improved to allow shuffles
that use the same operand twice or in reverse order. For example, ilvev
used to accept masks of the form:
<0, n, 2, n+2, 4, n+4, ...>
but now accepts:
<0, 0, 2, 2, 4, 4, ...>
<n, n, n+2, n+2, n+4, n+4, ...>
<0, n, 2, n+2, 4, n+4, ...>
<n, 0, n+2, 2, n+4, 4, ...>
One further improvement is that splati.[bhwd] is now the preferred instruction
for splat-like operations. The other special shuffles are no longer used
for splats. This lead to the discovery that <0, 0, ...> would not cause
splati.[hwd] to be selected and this has also been fixed.
This fixes the enc-3des test from the test-suite on Mips64r6 with MSA.

This changes the ABI used on 32-bit x86 for passing vector arguments.
Historically, clang passes the first 4 vector arguments in-register, and additional vector arguments on the stack, regardless of platform. That is different from the behavior of gcc, icc, and msvc, all of which pass only the first 3 arguments in-register.
The 3-register convention is documented, unofficially, in Agner's calling convention guide, and, officially, in the recently released version 1.0 of the i386 psABI.
Darwin is kept as is because the OS X ABI Function Call Guide explicitly documents the current (4-register) behavior.
This fixes PR21510

Before:
[call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.
aaaaaaaa];
After:
[call aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa.aaaaaaaa
.aaaaaaaa];
This merely papers over the fact that we aren't parsing ObjC method calls
correctly. Also, the indentation is weird.

Without the --target flag, clang uses the mips64 triple which selects the n64 abi. We need to add --target=mips-linux-gnu, so that clang can select the correct abi for mips32r2.

Summary:
This patch does 2 main things:
1. Enable sized delete if the feature test macro `__cpp_sized_deallocation` is enabled.
2. Rework and cleanup all of the sized delete tests.
Test Plan:
The sized delete replacement tests are now split into 4 files:
1. sized_delete11.pass.cpp: Ensure overriding sized delete in C++11 has no effect.
2. sized_delete14.pass.cpp: Test overriding sized delete in C++14 and ensure it is called. This test fails on clang and GCC < 5.1.
3. size_delete_calls_unsized_delete_.pass.cpp: Test that the default sized delete calls unsized delete.
4. sized_delete_fsizeddeallocation.pass.cpp: Test overriding sized delete when -fsized-deallocation is passed. This test should pass on clang and GCC >= 5.1
I have also removed a lot of cruft from the old tests. They no longer replace the new handler and tests that it is called for bad allocations.

This cleans up the FoldConstantArithmetic code by factoring out the case
of two ConstantSDNodes into an own function. This avoids unnecessary
complexity for many callers who already have ConstantSDNode arguments.
This also avoids an intermeidate SmallVector datastructure and a loop
over that datastructure.

VarDeclBitfields contained bits which are never present in parameters.
Split these out so that ParmVarDeclBitfields wouldn't grow past 32-bits
if another field was added.

On 64-bit targets, Function has 4-bytes of padding in its struct layout.
This uses the space for the intrinsic ID. It is set and recalculated whenever the function name is set. This is similar to the current behavior which clears the function from the intrinsic ID cache when its renamed.
The intrinsic cache itself is removed as the only purpose was to speedup calls to getIntrinsicID() which now just reading the new field in the struct.

This reverts commit r237210.
Also fix X86/complex-fca.ll to match the code that we used to generate
on win32 and now generate everwhere to conform to SysV.
