a199652a3e Change all self assignments X=X to (void)X, so that we can turn on a 
new gcc warning that complains on self-assignments and
self-initializations.

65c5243bd6 rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

e11d870459 Remove target specific node MipsISD::CMov, which is not used because all conditional moves are directly matched using tablegen patterns. If there's a need in the future, we can introduce it again

0e14644599 Match a pattern generated by a dag combiner opt where: 
(select (load (load tga0)) (load tga1)) => (load (select (load tga0) tga1))

Thanks to Akira for pointing that.

cec3b226a4 move all the target's asmprinters into the main target. The piece 
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

3bf2a701a5 In the calling convention logic, ValVT is always a legal type, 
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

f6e5e02c9b Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

55043ef46a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

0fa595f073 Fix PR7174, a couple o Mips fixes: 
- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

7af3eff94d RISC architectures get their memory operand folding for free. 
The only folding these load/store architectures can do is converting COPY into a
load or store, and the target independent part of foldMemoryOperand already
knows how to do that.

bd7194d21c Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). This 
addresses a longstanding deficiency noted in many FIXMEs scattered
across all the targets.

This effectively moves the problem up one level, replacing eleven
FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path
through FastISel where we actually supply a DebugLoc, fixing Radar
7421831.
