R600/SI: Fix bug in VGPR spilling
AMDGPU::SI_SPILL_V96_RESTORE was missing from a switch statement, which

R600/SI: add pass to mark CF live ranges as non-spillable
Spilling can insert instructions almost anywhere, and this can mess
up control flow lowering in a multitude of ways, due to instruction
reordering. Let's sort this out the easy way: never spill registers
involved with control flow, i.e. saved EXEC masks.
Unfortunately, this does not work at all with optimizations disabled,
as the register allocator ignores spill weights. This should be
addressed in a future commit.
The test was reduced from the "stacks" shader of [1]. Some issues
trigger the machine verifier while another one is checked manually.

v2: only insert pass with optimizations enabled, merge test runs.

CodeGen: match up correct insertvalue indices when assessing tail
calls.
When deciding whether a value comes from the aggregate or inserted
value of an insertvalue instruction, we compare the indices against
those of the location we're interested in. One of the lists needs
reversing because the input data is backwards (so that modifications
take place at the end of the SmallVector), but we were reversing both
before leading to incorrect results.

CodeGen: move over-zealous assert into actual if statement.
It's quite possible to encounter an insertvalue instruction that's
more deeply nested than the value we're looking for, but when that
happens we really mustn't compare beyond the end of the index array.
Since I couldn't see any guarantees about what comparisons std::equal
makes, we probably need to directly check the size beforehand. In
practice, I suspect most std::equal implementations would probably
bail early, which would be OK. But just in case...

It introduced two regressions (MultiSource/Benchmarks/tramp3d-v4/tramp3d-v4, and
MultiSource/Applications/kimwitu++/kc) on 3 out of 23 cross-compilation
test-runs used by Mips for release validation.
The issue is that on 64-bit targets comparisons such as BEQ compare the whole
GPR64 but incorrectly tell the instruction selector that they operate on
GPR32's. This leads to the elimination of i32->i64 extensions that are actually
required by comparisons to work correctly.

AArch64: Safely handle the incoming sret call argument.
This adds a safe interface to the machine independent InputArg struct
for accessing the index of the original (IR-level) argument. When a
non-native return type is lowered, we generate the hidden
machine-level sret argument on-the-fly. Before this fix, we were
representing this argument as OrigArgIndex == 0, which is an outright
lie. In particular this crashed in the AArch64 backend where we
actually try to access the type of the original argument.
Now we use a sentinel value for machine arguments that have no
original argument index. AArch64, ARM, Mips, and PPC now check for this
case before accessing the original argument.

Constant folding for shift IR instructions ignores all bits above 32 of
second argument (shift amount).
Because of that, some undef results are not recognized and APInt can
raise an assert failure if second argument has more than 64 bits.

This pass will always try to insert llvm.SI.ifbreak intrinsics

a problem when conditions for breaks or continue are computed outside
of the loop, because the llvm.SI.ifbreak intrinsic ends up being inserted
