Following on from D88890, this makes the newly added patterns
conditional on NoFP32Denormals. mad/mac f32 instructions always flush
denormals regardless of the MODE register setting, and I believe the
legacy variants do the same.

[InstCombine] Support lshr(trunc(lshr(x,c1)), c2) -> trunc(lshr(lshr(x,c1),c2)) uniform vector tests

FoldShiftByConstant is hardcoded for scalar/uniform outer shift amounts atm so that needs to be fixed first to support non-uniform cases

Async execute operation can take async arguments as dependencies.

Change `async.execute` custom parser/printer format to use `%value as %unwrapped: !async.value<!type>` sytax.

There were some existing tests that were not super useful. New ones are
added for testing MVE specific patterns.

Reformat to avoid unrelated changes in diff of future patch.
Committed as obvious.

Note: we already fold srem to undef if any denominator vector element is undef.

There might be a better way to specify the pre-conditions,
but this is hopefully clearer than the way it was written:
https://rise4fun.com/Alive/Jhk3

  Pre: C2 < 0 && isShiftedMask(C2) && (C1 == C1 & C2)
  %a = and %x, C2
  %r = add %a, C1
  =>
  %a2 = add %x, C1
  %r = and %a2, C2

[InstCombine] Add tests for X shift (A srem B) -> X shift (A and B-1) pow2 nonuniform constant vectors

Extended -cl-std/std flag with CL3.0 and added predefined version macros.

To make sure we don't store a mutable object (which could be modified by
outside code without us noticing) as the cache key, we pickle the cache
key to get a byte stream. If two keys are unequal, we know for sure they
will not have the same pickling. And if they are equal, there's a large
chance they will have the same pickling. If they don't, we might end up
not reusing a cached entry when we could have, but at least the behavior
we'll have is semantically correct.

Without this, legalization might not recursively handle child ops properly.

I messed up runlines in the original commit.

This patch extracts the ExprMutAnalyzer changes from https://reviews.llvm.org/D54943
into its own revision for simpler review and more atomic changes.

The analysis results are improved. Nested expressions (e.g. conditional
operators) are now detected properly. Some edge cases, especially
template induced imprecisions are improved upon.

IV widening is sometimes a strictly harmful transform (some examples
of this are shown in tests 11, 12 in widen-loop-comp.ll). One of the
reasons of this is that sometimes SCEV fails to prove some facts after
part of guards has been widened.

Though each single such case looks like a bug that can be addressed,
it seems that disabling of IV widening may be profitable in some cases.
We want to have an option to do so. By default, existing behavior is
preserved and IV widening is on.

When attempting to compute a differential orderIndex we were calculating the
bailout condition correctly, but then an errant "+ 1" meant the orderIndex we
created was invalid.
