Jakob Stoklund Olesen 0965585cb1 Experimental support for aligned NEON spills.
ARM targets with NEON units have access to aligned vector loads and
stores that are potentially faster than unaligned operations.

Add support for spilling the callee-saved NEON registers to an aligned
stack area using 16-byte aligned NEON loads and store.

This feature is off by default, controlled by an -align-neon-spills
command line option.

Bob Wilson 1a74de9504 Add variants of the dispatchsetup pseudo for Thumb and !VFP. <rdar://10620138>
My change r146949 added register clobbers to the eh_sjlj_dispatchsetup pseudo
instruction, but on Thumb1 some of those registers cannot be used.  This
caused massive failures on the testsuite when compiling for Thumb1.  While
fixing that, I noticed that the eh_sjlj_setjmp instruction has a "nofp"
variant, and I realized that dispatchsetup needs the same thing, so I have
added that as well.

Benjamin Kramer d90b595599 Reenable building with -fvisibility-inlines-hidden.
This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.

We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).

IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

Chandler Carruth b024aa021d Make the unreachable probability much much heavier. The previous
probability wouldn't be considered "hot" in some weird loop structures
or other compounding probability patterns. This makes it much harder to
confuse, but isn't really a principled fix. I'd actually like it if we
could model a zero probability, as it would make this much easier to
reason about. Suggestions for how to do this better are welcome.

Chris Lattner eaf9b7629a Fix a nasty bug in the type remapping stuff that I added that is breaking kc++ on
the build bot in some cases.  The basic issue happens when a source module contains
both a "%foo" type and a "%foo.42" type.  It will see the later one, check to see if
the destination module contains a "%foo" type, and it will return true... because
both the source and destination modules are in the same LLVMContext.  We don't want
to map source types to other source types, so don't do the remapping if the mapped
type came from the source module.

Unfortunately, I've been unable to reduce a decent testcase for this, kc++ is 
pretty great that way.

Jakob Stoklund Olesen b95c102c2f Heed spill slot alignment on ARM.
Use the spill slot alignment as well as the local variable alignment to
determine when the stack needs to be realigned. This works now that the
ARM target can always realign the stack by using a base pointer.

Still respect the ARMBaseRegisterInfo::canRealignStack() function
vetoing a realigned stack.  Don't use aligned spill code in that case.

Chandler Carruth 24680c24d8 Begin teaching the X86 target how to efficiently codegen patterns that
use the zero-undefined variants of CTTZ and CTLZ. These are just simple
patterns for now, there is more to be done to make real world code using
these constructs be optimized and codegen'ed properly on X86.

The existing tests are spiffed up to check that we no longer generate
unnecessary cmov instructions, and that we generate the very important
'xor' to transform bsr which counts the index of the most significant
one bit to the number of leading (most significant) zero bits. Also they
now check that when the variant with defined zero result is used, the
cmov is still produced.

Bob Wilson 75f12cc3fe Mark ARM eh_sjlj_dispatchsetup as clobbering all registers. Radar 10567930.
We used to rely on the *eh_sjlj_setjmp instructions to mark that a function
with setjmp/longjmp exception handling clobbers all the registers.  But with
the recent reorganization of ARM EH, those eh_sjlj_setjmp instructions are
expanded away earlier, before PEI can see them to determine what registers to
save and restore.  Mark the dispatchsetup instruction in the same way, since
that instruction cannot be expanded early.  This also more accurately reflects
when the registers are clobbered.

"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's

Evan Cheng 4266a79351 Add a if-conversion optimization that allows 'true' side of a diamond to be
unpredicated. That is, turn
 subeq  r0, r1, #1
 addne  r0, r1, #1                                                                                                                                                                                                     
into
 sub    r0, r1, #1
 addne  r0, r1, #1

For targets where conditional instructions are always executed, this may be
beneficial. It may remove pseudo anti-dependency in out-of-order execution
CPUs. e.g.
 op    r1, ...
 str   r1, [r10]        ; end-of-life of r1 as div result
 cmp   r0, #65
 movne r1, #44  ; raw dependency on previous r1
 moveq r1, #12

If movne is unpredicated, then
 op    r1, ...
 str   r1, [r10]
 cmp   r0, #65
 mov   r1, #44  ; r1 written unconditionally
 moveq r1, #12

Both mov and moveq are no longer depdendent on the first instruction. This gives
the out-of-order execution engine more freedom to reorder them.

This has passed entire LLVM test suite. But it has not been enabled for any ARM
variant pending more performance evaluation.
