5464c301c4 AArch64: stop claiming that NEON registers are usable for now.
If vector types have legal register classes, then LLVM bypasses LegalizeTypes
on them, which causes faults currently since the code to handle them isn't in
place.

This fixes test failures when AArch64 is the default target.

b1d081230e Make ARMAsmParser accept the correct alignment specifier syntax in instructions.
The parser will now accept instructions with alignment specifiers written like
    vld1.8  {d16}, [r0:64]
, while also still accepting the incorrect syntax
    vld1.8  {d16}, [r0, :64]

382a5530ec Don't asume that a static function in an extern "C" block will not be mangled.
Since functions with internal linkage don't have language linkage, it is valid
to overload them:

extern "C" {
       static int foo();
       static int foo(int);
}

So we mangle them.

6b9d461780 For Mips 16, add the optimization where the 16 bit form of addiu sp can be used
if the offset fits in 11 bits. This makes use of the fact that the abi
requires sp to be 8 byte aligned so the actual offset can fit in 8
bits. It will be shifted left and sign extended before being actually used.
The assembler or direct object emitter will shift right the 11 bit
signed field by 3 bits. We don't need to deal with that here.

f09e02f01a X86: Disable generation of rep;movsl when %esi is used as a base pointer.
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

and freebsd a 4 byte stack alignment.

7eacad03ef [NVPTX] Disable vector registers
Vectors were being manually scalarized by the backend.  Instead,
let the target-independent code do all of the work.  The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

6158ad1bc7 R600: Fix regression with shadow array sampler on pre-SI GPUs.
'R600/SI: Use proper instructions for array/shadow samplers.' removed two
cases from TEX_SHADOW. Vincent Lejeune reported on IRC that this broke some
shadow array piglit tests with the r600g driver. Reinstating the removed
cases should fix this, and still works with radeonsi as well.

I will follow up with some lit tests which would have caught the regression.

092e5e7566 Currently, codegen may spent some time in SDISel passes even if an entire
function is successfully handled by fast-isel. That's because function
arguments are *always* handled by SDISel. Introduce FastLowerArguments to
allow each target to provide hook to handle formal argument lowering.

As a proof-of-concept, add ARMFastIsel::FastLowerArguments to handle
functions with 4 or fewer scalar integer (i8, i16, or i32) arguments. It
completely eliminates the need for SDISel for trivial functions.

fb55a8fd7c ARM cost model: Address computation in vector mem ops not free
Adds a function to target transform info to query for the cost of address
computation. The cost model analysis pass now also queries this interface.
The code in LoopVectorize adds the cost of address computation as part of the
memory instruction cost calculation. Only there, we know whether the instruction
will be scalarized or not.
Increase the penality for inserting in to D registers on swift. This becomes
necessary because we now always assume that address computation has a cost and
three is a closer value to the architecture.
