This tries to keep all the ModRM memory and register forms in their own regions of the encodings. Hoping to make it simple on some of the switch statements that operate on these encodings.

The gold-plugin was doing this internally, now the API is handling
commons correctly based on the given resolution.

Summary:
We previously added these output sections to segments just by type.
Therefore, if there's a PHDRS command like this
PHDRS {
headers PT_PHDR PHDRS;
interp PT_INTERP;
}
SECTIONS {
. = SIZEOF_HEADERS;
.interp : { *(.interp) } :text
}
then .interp was added to "interp" segment even though the linker
is not instructed to do so by SECTIONS command. This patch removes
the default behavior to simplify.

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.

Dump polyhedral descriptions of Scops optimized with the isl scheduling
optimizer and the set of post-scheduling transformations applied
on the schedule tree to be able to check the work of the IslScheduleOptimizer

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.
Changes are hidden behind -asan-experimental-poisoning flag.
