Chris Lattner edb9d84dcc add targetoperand flags for jump tables, constant pool and block address
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

Chris Lattner df8e17d80b implement support for the MO_DARWIN_STUB TargetOperand flag,
and have isel apply to to call operands as required.  This allows
us to get $stub suffixes on label references on ppc/tiger with the

Duncan Sands 71049f78ed In the calling convention logic, ValVT is always a legal type,

EVT is not needed.  Use MVT for ValVT everywhere.

Duncan Sands f5dda01f33 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.

Chris Lattner 0e023ea02a 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.

Evan Cheng bf4070756f Teach if-converter to be more careful with predicating instructions that would
take multiple cycles to decode.
For the current if-converter clients (actually only ARM), the instructions that
are predicated on false are not nops. They would still take machine cycles to
decode. Micro-coded instructions such as LDM / STM can potentially take multiple
cycles to decode. If-converter should take treat them as non-micro-coded
simple instructions.

Jakob Stoklund Olesen 7de379467e Replace the SubRegSet tablegen class with a less error-prone mechanism.
A Register with subregisters must also provide SubRegIndices for adressing the

CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
index that returns the same register, and ARM NEON Q registers where both D
subregs have ssub_0 and ssub_1 sub-subregs.

It is now required that all subregisters are named by an index, and a future

Dale Johannesen d7d6638e3e The PPC MFCR instruction implicitly uses all 8 of the CR

VCMPEQ instructions that feed into it getting deleted.
If it is so marked, local RA complains about this sequence:
 vreg = MCRF  CR0
 MFCR  <kill of whatever preg got assigned to vreg>
All current uses of this instruction are only interested in
one of the 8 CR registers, so redefine MFCR to be a normal
unary instruction with a CR input (which is emitted only as
a comment).  That avoids all problems.  7739628.
