Chandler Carruth c2fd56a21d Remove some unused private fields from the AArch64MCCodeEmitter. These
fields were only ever set in the constructor. The create method retains
its consistent interface so that these bits can be re-threaded through
the emitter if they're ever needed.

This was found by the -Wunused-private-field Clang warning.

Tim Northover 67d3c09332 AArch64: adjust tests which rely on a default JIT
Profiling tests *do* need a JIT. They'll pass if a cross-compiler targetting
AArch64 by default has been built, but fail if a native AArch64 compiler has
been build. Therefore XFAIL is inappropriate and we mark them unsupported.

ExecutionEngine tests are JIT by definition, they should also be unsupported.

Transforms/LICM only uses the interpreter to check the output is still sane
after optimisation. It can be switched to use an interpreter.

Hal Finkel 76e65e4542 BBVectorize: Fix an invalid reference bug
This fixes PR15289. This bug was introduced (recently) in r175215; collecting
all std::vector references for candidate pairs to delete at once is invalid
because subsequent lookups in the owning DenseMap could invalidate the
references.

bugpoint was able to reduce a useful test case. Unfortunately, because whether
or not this asserts depends on memory layout, this test case will sometimes
appear to produce valid output. Nevertheless, running under valgrind will
reveal the error.

Cameron Zwarich ddeabf78a0 Fix a conversion from a forward iterator to a reverse iterator in
MachineBasicBlock::SplitCriticalEdge. Since this is an iterator rather than
an instr_iterator, the isBundled() check only passes if getFirstTerminator()
returned end() and the garbage memory happens to lean that way.

Multiple successors can be present without any terminator instructions in the
case of exception handling with a fallthrough.

Cameron Zwarich bfebb41984 Add support for updating the LiveIntervals of registers used by 'exotic'
terminators that actually have register uses when splitting critical edges.

This commit also introduces a method repairIntervalsInRange() on LiveIntervals,
which allows for repairing LiveIntervals in a small range after an arbitrary
target hook modifies, inserts, and removes instructions. It's pretty limited
right now, but I hope to extend it to support all of the things that are done
by the convertToThreeAddress() target hooks.

Bill Wendling 23242098e7 The transform is:
(or (bool?A:B),(bool?C:D)) --> (bool?(or A,C):(or B,D))

By the time the OR is visited, both the SELECTs have been visited and not
optimized and the OR itself hasn't been transformed so we do this transform in
the hopes that the new ORs will be optimized.

The transform is explicitly disabled for vector-selects until "codegen matures
to handle them better".

Reed Kotler 8cf5103b2b Use a different scheme to chose 16/32 variants. This scheme is more
consistent with how BuildMI works. No new tests needed. All should work
the same as before.

Chad Rosier 925c9b499e [ms-inline asm] Do not omit the frame pointer if we have ms-inline assembly.
If the frame pointer is omitted, and any stack changes occur in the inline
assembly, e.g.: "pusha", then any C local variable or C argument references
will be incorrect.  

I pass no judgement on anyone who would do such a thing. ;)

Chad Rosier 42d4e2e4ec c[ms-inline asm] It's possible to have a SizeDirective rewrite and an
Input/Output rewrite to the same location.  Make sure the SizeDirective rewrite
is performed first.  This also ensure the sort algorithm is stable.

Derek Schuff 8878bcc9e7 If bundle alignment is enabled, do not add data to a fragment with instructions
With bundle alignment, instructions all get their own MCFragments
(unless they are in a bundle-locked group). For instructions with
fixups, this is an MCDataFragment. Emitting actual data (e.g. for
.long) attempts to re-use MCDataFragments, which we don't want int
this case since it leads to fragments which exceed the bundle size.
So, don't reuse them in this case.
Also adds a test and fixes some formatting.

Bill Wendling aef9c37c65 Use the 'target-features' and 'target-cpu' attributes to reset the subtarget features.
If two functions require different features (e.g., `-mno-sse' vs. `-msse') then
we want to honor that, especially during LTO. We can do that by resetting the
subtarget's features depending upon the 'target-feature' attribute.
