Chris Lattner 4a5f7be077 fix CodeGenTarget::getRegisterVTs to not return the 
same vt multiple times for a register.  For example,
ECX is in 5 different i32 reg classes, just return 
1 i32 instead of 5.

Chris Lattner 7bc5d9b576 hoist some funky logic into CodeGenInstruction 
from two places in CodeGenDAGPatterns.cpp, and
use it in DAGISelMatcherGen.cpp instead of using
an incorrect predicate that happened to get lucky
on our current targets.

Chris Lattner d44966f26d continue pushing tblgen's support for nodes with multiple 
results forward.  We can now handle an instruction that 
produces one implicit def and one result instead of one or
the other when not at the root of the pattern.

Chris Lattner e7e9f06d3b fix a bug in my recent patch that increased opcode size to 2 bytes: 
the index comments nested under OPC_SwitchOpcode were off by one.
This fixes the comments.

Eric Christopher 81c03447fc When we promote a load of an argument make sure to take the alignment 
of the previous load - it's usually important.  For example, we don't want
to blindly turn an unaligned load into an aligned one.

Johnny Chen 6094cdab9f Add NVMulSLFrm to represent "3-register multiply with scalar" operations and set 
it as the format for the appropriate N3V*SL*<> classes.  These instructions
require special handling of the M:Vm field which encodes the restricted Dm and
the lane index within Dm.

Examples are A8.6.325 VMLA, VMLAL, VMLS, VMLSL (by scalar):

	vmlal.s32	q3, d2, d10[0]

Jim Grosbach 44313db557 Thumb2 storeFrom/LoadToStackSlot() need to handle tGPR regs directly, not pass 
through to the generic version. The generic functions use STR/LDR, but T2
needs the t2STR/t2LDR instead so we get the addressing mode correct.

Johnny Chen 93acfbf441 Remove the duplicate multiclass N3VSh_QHSD and use N3VInt_QHSD which is modified 
to now take a format argument.  N3VDInt<> and N3VQInt<> are modified to take a
format argument as well.

Bill Wendling d1aa77c37d If we mark clean-ups as clean-ups, then it could break when inlining through an 
'invoke' instruction. You will get a situation like this:

bb:
  %ehptr = eh.exception()
  %sel = eh.selector(%ehptr, @per, 0);

...

bb2:
  invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

lpad:
  ...

The unwinder will see the %sel call as a clean-up and, if it doesn't have a
catch further up the call stack, it will skip running it. But there *is* another
catch up the stack -- the catch for the %lpad. However, we can't see that. This
is fixed in code-gen, where we detect this situation, and convert the "clean-up"
selector call into a "catch-all" selector call. This gives us the correct
semantics.

Johnny Chen 0b57de3c4c Add NVExtFrm to represent NEON Vector Extract Instructions, that uses Inst{11-8} 
to encode the byte location of the extracted result in the concatenation of the
operands, from the least significant end.

Modify VEXTd and VEXTq classes to use the format.

Johnny Chen 2cf04957c2 Add N3RegVShFrm to represent 3-Register Vector Shift Instructions, which do not 
follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm.  The operand order of
N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand).

Add a parent class N3Vf which requires passing a Format argument and which the
N3V class is modified to inherit from.  N3V class represents the "normal"
3-Register NEON Instructions with N3RegFrm.

Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift
Instructions and replace 8 invocations with it.
