The callers still have ConstantInt guards, so there is no functional change
intended from this change. But relaxing the callers will allow more folds
for vector types.

getAccessFunctions() is dead code and the 'BB' argument
of getOrCreateAccessFunctions() is not used. This patch deletes
getAccessFunctions and transforms AccFuncMap into
a std::vector<std::unique_ptr<MemoryAccess>> AccessFunctions.

In some cases, FastIsel was emitting TEST instruction with K reg input, which is illegal.
Changed to using KORTEST when dealing with K regs.

This fixes the crash from PR29072, where the MachineBasicBlock::iterator
wasn't being properly checked against MachineBasicBlock::end() before
iterating. This was another bug exposed by the new
ilist::iterator::operator*() assertion from r279314.
This testcase is poor quality. bugpoint couldn't reduce any further,
and I haven't had time to dig into what's going on so I can't invent a
better one. I didn't even get good CHECK lines in: this is just a
crasher.
I'm committing anyway since this is a real crash with an obvious fix,
but I'll leave PR29072 open and ask an ARM maintainer to help improve
the testcase.

Summary:
We can insert function call instead of multiple store operation.
Current default is blocks larger than 64 bytes.

This replaces the old approach of fingerprinting every AST node into a string,
which avoided collisions and was simple to implement, but turned out to be
extremely ineffective with respect to both performance and memory.
The collisions are now dealt with in a separate pass, which no longer causes
performance problems because collisions are rare.

This is valid in GNU C, which allows pointers to incomplete enums. GCC

The test case included in r279125 exposed existing undefined behavior in the
SLP vectorizer that it did not introduce. This patch reapplies the original
patch, but modifies the test case to avoid hitting the undefined behavior. This
allows us to close PR28330 while keeping the UBSan bot happy. The undefined
behavior the original test uncovered will be addressed in a follow-on patch.

TLS on i386 in non-PIE/PIC code seems broken right now, because we don't
properly add the addend encoded in the instruction to the resulting
offset when processing R_386_TLS_LE relocations.
Extend one of the existing tests for TLS on i686 to use an addend.

So far macro-generated code was treated by the CloneDetector as normal code.
This caused that some macros where reported as false-positive clones because
large chunks of code coming from otherwise concise macro expansions were treated
as copy-pasted code.
This patch ensures that macros are treated in the same way as literals/function
calls. This prevents macros that expand into multiple statements
from being reported as clones.

unit for use in the PreservedAnalyses set.
This doesn't have any important functional change yet but it cleans
things up and makes the analysis substantially more efficient by
avoiding querying through the type erasure for every analysis.
I also think it makes it much easier to reason about how analyses are
preserved when walking across pass managers and across IR unit
abstractions.
Thanks to Sean and Mehdi both for the comments and suggestions.
