Chris Lattner 3fdf98c60f By popular demand, link up types by name if they are isomorphic and one is an 
autorenamed version of the other.   This makes the IR easier to read, because
we don't end up with random renamed versions of the types after LTO'ing a large app.

Craig Topper a4d411cb1b Don't try to match 'unpackl/h v, v' for 32xi8 and 16xi16 when only AVX1 is supported. Fix 'unpackh v, v' for 256-bit types to understand 128-bit lanes.

Eli Friedman 16ad2905a3 Make loop preheader insertion in LoopSimplify handle the case where the loop header is a landing pad correctly (by splitting the landingpad out of the loop header). Make some adjustments to the rest of LoopSimplify to make it clear that the rest of LoopSimplify isn't making bad assumptions about the presence of landing pads. PR11575.

Dan Gohman 75d7d5e988 Move Instruction::isSafeToSpeculativelyExecute out of VMCore and 
into Analysis as a standalone function, since there's no need for
it to be in VMCore. Also, update it to use isKnownNonZero and
other goodies available in Analysis, making it more precise,
enabling more aggressive optimization.

Devang Patel c268688643 Do not sink instruction, if it is not profitable. 
On ARM, peephole optimization for ABS creates a trivial cfg triangle which tempts machine sink to sink instructions in code which is really straight line code. Sometimes this sinking may alter register allocator input such that use and def of a reg is divided by a branch in between, which may result in extra spills. Now mahine sink avoids sinking if final sink destination is post dominator.

Jim Grosbach 8d24618975 ARM NEON VST2 assembly parsing and encoding. 
Work in progress. Parsing for non-writeback, single spaced register lists
works now. The rest have the representations better factored, but still
need more to be able to parse properly.

Dan Gohman bd944b4153 It turns out that clang does use pointer-to-function types to 
point to ARC-managed pointers sometimes. This fixes rdar://10551239.

Jim Grosbach a342667fd0 ARM/Thumb2 'cmp rn, #imm' alias to cmn. 
When 'cmp rn #imm' doesn't match due to the immediate not being representable,
but 'cmn rn, #-imm' does match, use the latter in place of the former, as
it's equivalent.

Evan Cheng 7fae11b231 - Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a function 
to finalize MI bundles (i.e. add BUNDLE instruction and computing register def
  and use lists of the BUNDLE instruction) and a pass to unpack bundles.
- Teach more of MachineBasic and MachineInstr methods to be bundle aware.
- Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to
  prevent IT blocks from being broken apart.

Akira Hatanaka e41963ce47 Relocation against a symbol, instead of against section. We had some extreme 
test cases where there were a lot of relocations applied relative to a large
rodata section. Gas would create a symbol for each of these whereas we would
be relative to the beginning of the rodata section. This change mimics what
gas does.

Bob Wilson fadc2c83e5 Implement 'e' and 'f' modifiers for Neon inline asm. <rdar://problem/10551006> 
These modifiers simply select either the low or high D subregister of a Neon
Q register.  I've also removed the unimplemented 'p' modifier, which turns out
to be a bit different than the comment here suggests and as far as I can tell
was only intended for internal use in Apple's version of gcc.
