[InstCombine] allow more than one use for vector bitcast folding with selects
The motivating example for this transform is similar to D20774 where bitcasts interfere
with a single cmp/select sequence, but in this case we have 2 uses of each bitcast to
produce min and max ops:
define void @minmax_bc_store(<4 x float> %a, <4 x float> %b, <4 x float>* %ptr1, <4 x float>* %ptr2) {
%cmp = fcmp olt <4 x float> %a, %b
%bc1 = bitcast <4 x float> %a to <4 x i32>
%bc2 = bitcast <4 x float> %b to <4 x i32>
%sel1 = select <4 x i1> %cmp, <4 x i32> %bc1, <4 x i32> %bc2
%sel2 = select <4 x i1> %cmp, <4 x i32> %bc2, <4 x i32> %bc1
%bc3 = bitcast <4 x float>* %ptr1 to <4 x i32>*
store <4 x i32> %sel1, <4 x i32>* %bc3
%bc4 = bitcast <4 x float>* %ptr2 to <4 x i32>*
store <4 x i32> %sel2, <4 x i32>* %bc4
ret void
}
With this patch, we move the selects up to use the input args which allows getting rid of
all of the bitcasts:
define void @minmax_bc_store(<4 x float> %a, <4 x float> %b, <4 x float>* %ptr1, <4 x float>* %ptr2) {
%cmp = fcmp olt <4 x float> %a, %b
%sel1.v = select <4 x i1> %cmp, <4 x float> %a, <4 x float> %b
%sel2.v = select <4 x i1> %cmp, <4 x float> %b, <4 x float> %a
store <4 x float> %sel1.v, <4 x float>* %ptr1, align 16
store <4 x float> %sel2.v, <4 x float>* %ptr2, align 16
ret void
}
The asm for x86 SSE then improves from:
movaps %xmm0, %xmm2
cmpltps %xmm1, %xmm2
movaps %xmm2, %xmm3
andnps %xmm1, %xmm3
movaps %xmm2, %xmm4
andnps %xmm0, %xmm4
andps %xmm2, %xmm0
orps %xmm3, %xmm0
andps %xmm1, %xmm2
orps %xmm4, %xmm2
movaps %xmm0, (%rdi)
movaps %xmm2, (%rsi)
To:
movaps %xmm0, %xmm2
minps %xmm1, %xmm2
maxps %xmm0, %xmm1
movaps %xmm2, (%rdi)
movaps %xmm1, (%rsi)
The TODO comments show that we're limiting this transform only to vectors and only to bitcasts
because we need to improve other transforms or risk creating worse codegen.

[ARM] Add support for mrrc/mrrc2 intrinsics.
Reapplying patch as it was reverted when it was first

mrrc2 intrinsic was called in ARM mode. The failure
was happening because the instruction was being built
in ARMISelDAGToDAG.cpp and the tablegen description for
mrrc2 instruction doesn't allow you to use a predicate.
The ARM architecture manuals do say that mrrc2 in ARM
mode can be predicated with AL in assembly but this has
no effect on the encoding of the instruction as the top
4 bits will always be 1111 not 1110 which is the encoding

There is a non-functional but behaviorial change in WinException --
earlier if `getFrameIndexReferenceFromSP` failed we'd trip an assert,
but now we'll silently use the (wrong) offset from the base pointer. I
could not write the assert I'd like to write ("FrameReg ==
StackRegister", like I've done in X86FrameLowering) since there is no
easy way to get to the stack register from WinException (happy to be
proven wrong here). One solution to this is to add a `bool
OnlyStackPointer` parameter to `getFrameIndexReferenceFromSP` that
asserts if it could not satisfy its promise of returning an offset from
a stack pointer, but that seems overkill.

When calculating a square root using Newton-Raphson with two constants,
a naive implementation is to use five multiplications (four muls to calculate
reciprocal square root and another one to calculate the square root itself).
However, after some reassociation and CSE the same result can be obtained
with only four multiplications. Unfortunately, there's no reliable way to do
such a reassociation in the back-end. So, the patch modifies NR code itself
so that it directly builds optimal code for SQRT and doesn't rely on any

Don't print (PLT) on arm.
The R_ARM_PLT32 relocation is deprecated and is not produced by MC.
This means that the code being deleted is dead from the .o point of
view and was making the .s more confusing.

Remove redundant -mattr options from llvm-objdump commands.
The -mattr options in these four tests have no effect on the output of
llvm-objdump. In the case of the two Mips tests, removing the -mattr option
left duplicate RUN lines so the duplicates have been removed.

Both parameters to visitTypeBegin are actually members of CVRecord,
so we can just pass CVRecord instead of destructuring it.
