Add an option to llvm-profdata merge for writing out sparse indexed

Apparently MSVC won't allow you to ask for the sizeof() a data member at
class scope.

Loop transformations can sometimes fail because the loop, while in
valid rotated LCSSA form, is not in a canonical CFG form. This is
an extremely simple pass that just merges obviously redundant
blocks, which can be used to fix some known failure cases. In the
future, it may be enhanced with more cases (and have code shared with
SimplifyCFG).

This allows us to run LoopSimplifyCFG -> LoopRotate -> LoopUnroll,
so that SimplifyCFG cleans up the loop before Rotate tries to run.

Not currently used in the pass manager, since this pass doesn't do
anything unless you can hook it up in an LPM with other loop passes.
It'll be added once Chandler cleans up things to allow this.

Tested in a custom pipeline out of tree to confirm it works in
practice (in addition to the included trivial test).

The majority of attribute queries checks for the existence of an enum
attribute in the FunctionIndex slot. We only have 48 of those and can
therefore summarize them in an uint64_t bitset which measurably improves
compile time.

The majority of queries just checks for the existince of an enum
attribute.  We only have 48 of those and can summaryiz them in an
uint64_t bitfield so we can avoid searching the list. This improves
"opt" compile time by 1-4% in my measurements.

[InstCombine] avoid an insertelement transformation that induces the opposite extractelement fold (PR26354)

We would infinite loop because we created a shufflevector that was wider than
needed and then failed to combine that with the insertelement. When subsequently
visiting the extractelement from that shuffle, we see that it's unnecessary,
delete it, and trigger another visit to the insertelement.

This support is _very_ rudimentary, just enough to get some basic data
into the CodeView debug section.

Left to do is:
- Use the combined opcodes to save space.
- Do something about code offsets.

The basic optimisation was to convert (mul $LHS, $complex_constant) into
roughly "(shl (mul $LHS, $simple_constant), $simple_amt)" when it was expected
to be cheaper. The original logic checks that the mul only has one use (since
we're mangling $complex_constant), but when used in even more complex
addressing modes there may be an outer addition that can pick up the wrong
value too.

I *think* the ARM addressing-mode problem is actually unreachable at the
moment, but that depends on complex assessments of the profitability of
pre-increment addressing modes so I've put a real check in there instead of an
assertion.

We already do this for case splits introduced as a result of defensive null
checks in functions and methods, so do the same for function-like macros.

- Include the position of the argument on which the nullability is violated
- Differentiate between a 'method' and a 'function' in the message wording
- Test for the error message text in the tests
- Fix a bug with setting 'IsDirectDereference' which resulted in regular dereferences assumed to have call context.
