Nadav Rotem c05d30601c Add a new optimization pass: Stack Coloring, that merges disjoint static allocations (allocas). Allocas are known to be 
disjoint if they are marked by disjoint lifetime markers (@llvm.lifetime.XXX intrinsics).

David Blaikie 986d76d7b3 Tidy up a few more uses of MF.getFunction()->getName(). 
Based on CR feedback from r162301 and Craig Topper's refactoring in r162347
here are a few other places that could use the same API (& in one instance drop
a Function.h dependency).

Craig Topper 96601ca332 Add a getName function to MachineFunction. Use it in places that previously did getFunction()->getName(). Remove includes of Function.h that are no longer needed.

Bill Wendling 0bcbd1df7a Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and 
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.

Chad Rosier 2531a6415f Add an ensureMaxAlignment() function to MachineFrameInfo (analogous to 
ensureAlignment() in MachineFunction).  Also, drop setMaxAlignment() in
favor of this new function.  This creates a main entry point to setting
MaxAlignment, which will be helpful for future work.  No functionality
change intended.

Rafael Espindola 95d594cac3 Teach CodeGen's version of computeMaskedBits to understand the range metadata. 
This is the CodeGen equivalent of r153747. I tested that there is not noticeable
performance difference with any combination of -O0/-O2 /-g when compiling
gcc as a single compilation unit.

Akira Hatanaka 6c2cf8b1fb Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which is 
needed to emit a 64-bit gp-relative relocation entry. Make changes necessary
for emitting jump tables which have entries with directive .gpdword. This patch
does not implement the parts needed for direct object emission or JIT.

Chris Lattner 73858d1689 Rewrite CanShareConstantPoolEntry to be implemented in terms of the 
mid-level constant folding APIs instead of doing its own analysis.
This makes it more general (e.g. can now share a <2 x i64> with a
<4 x i32>) and avoid duplicating a bunch of logic.

Chris Lattner 6b0dc92043 progress making the world safe to ConstantDataVector. While 
we're at it, allow PatternMatch's "neg" pattern to match integer
vector negations, and enhance ComputeNumSigned bits to handle
shl of vectors.

Evan Cheng e837dead3c - Rename TargetInstrDesc, TargetOperandInfo to MCInstrDesc and MCOperandInfo and 
sink them into MC layer.
- Added MCInstrInfo, which captures the tablegen generated static data. Chang
TargetInstrInfo so it's based off MCInstrInfo.

Cameron Zwarich 5567869637 MachineConstantPoolValues are not uniqued, so they need to be freed if they 
share entries. Add a DenseSet to MachineConstantPool for the MachineCPVs that
it owns.

This will hopefully fix the MC/ARM/elf-reloc-01.ll failure on the leaks bots.
