[MSSA] Add an overload for getClobberingMemoryAccess.
A seemingly common use for the walker's getClobberingMemoryAccess
function is:
```
MemoryAccess *getClobber(MemorySSAWalker *W, MemoryUseOrDef *MUD) {
const Instruction *I = MUD->getMemoryInst();
return W->getClobberingMemoryAccess(I);

Which is kind of redundant, since walkers will ultimately query MSSA to
find out which MemoryAccess `I` maps to (...which is always `MUD`).
So, this patch adds an overload of getClobberingMemoryAccess that

of getClobberingMemoryAccess becomes a lightweight wrapper around our

Additionally, this patch un`virtual`izes the Instruction overload of

Doing this also has the advantage that when doing the regular

Use ValueOffsetPair to enhance value reuse during SCEV expansion.
In D12090, the ExprValueMap was added to reuse existing value during SCEV expansion.
However, const folding and sext/zext distribution can make the reuse still difficult.
A simplified case is: suppose we know S1 expands to V1 in ExprValueMap, and
S1 = S2 + C_a
S3 = S2 + C_b
where C_a and C_b are different SCEVConstants. Then we'd like to expand S3 as
V1 - C_a + C_b instead of expanding S2 literally. It is helpful when S2 is a
complex SCEV expr and S2 has no entry in ExprValueMap, which is usually caused
by the fact that S3 is generated from S1 after const folding.
In order to do that, we represent ExprValueMap as a mapping from SCEV to
ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a} into the
ExprValueMap when we create SCEV for V1. When S3 is expanded, it will first
expand S2 to V1 - C_a because of S2->{V1, C_a} in the map, then expand S3 to
V1 - C_a + C_b.

Summary:
This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting).

[docs] Fixing Sphinx warnings to unclog the buildbot
Lots of blocks had "llvm" or "nasm" syntax types but either weren't following
the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type
doesn't even exist (nasm?).
Other documents had :options: what were invalid. I only removed those that had
warnings, and left the ones that didn't, in order to follow the principle of
least surprise.
This is like this for ages, but the buildbot is now failing on errors. It may
take a while to upgrade the buildbot's sphinx, if that's even possible, but
that shouldn't stop us from getting docs updates (which seem down for quite
a while).
Also, we're not losing any syntax highlight, since when it doesn't parse, it
doesn't colour. Ie. those blocks are not being highlighted anyway.
I'm trying to get all docs in one go, so that it's easy to revert later if we
do fix, or at least easy to know what's to fix.

[X86][SSE] Reimplement SSE fp2si conversion intrinsics instead of using generic IR
D20859 and D20860 attempted to replace the SSE (V)CVTTPS2DQ and VCVTTPD2DQ truncating conversions with generic IR instead.
It turns out that the behaviour of these intrinsics is different enough from generic IR that this will cause problems, INF/NAN/out of range values are guaranteed to result in a 0x80000000 value - which plays havoc with constant folding which converts them to either zero or UNDEF. This is also an issue with the scalar implementations (which were already generic IR and what I was trying to match).
This patch changes both scalar and packed versions back to using x86-specific builtins.
It also deals with the other scalar conversion cases that are runtime rounding mode dependent and can have similar issues with constant folding.

[ARM] Skip inline asm memory operands in DAGToDAGISel
Retry r275776 (no changes, we suspect the issue was with another commit).
The current logic for handling inline asm operands in DAGToDAGISel interprets
the operands by looking for constants, which should represent the flags
describing the kind of operand we're dealing with (immediate, memory, register
def etc). The operands representing actual data are skipped only if they are
non-const, with the exception of immediate operands which are skipped explicitly
when a flag describing an immediate is found.
The oversight is that memory operands may be const too (e.g. for device drivers
reading a fixed address), so we should explicitly skip the operand following a
flag describing a memory operand. If we don't, we risk interpreting that
constant as a flag, which is definitely not intended.

with sub-modules.
It *does not* try to argue whether sub-modules are better or worse than any other
Git solution, nor if Git is better than any other VCS, nor if GitHub is better
than any other free code hosting service. This is just the final conclusions of
48 days and 320 emails (plus a lot of IRC discussions) on the LLVM community.
This document will be presented at the survey that the foundation will setup for
us to decide if we move to this solution or not. It reflects what was discussed
on the lists, but it's not authoritative. If something is not clear enough,

The relocations R_ARM_TLS_LE12 and R_ARM_TLS_IE12GP are not
supported, I know of no ARM Toolchain that supports these relocations
as they limit the size of the TLS block.
No code relaxation is supported as the standard ARM TLS model puts
