Dan Gohman 8932bff7fe Fix the alignment requirements of several unpck and shuf instructions. 
Generalize isPSHUFDMask and add a unary SHUFPD pattern so that SHUFPD's
memory operand alignment can be tested as well, with a fix to avoid
breaking MMX's use of isPSHUFDMask.

Chris Lattner dc2cf228ce Replacing a cast with another one does not reduce the number of 
casts in the input.

Devang Patel a882328e61 Update dominator info for the middle blocks created while spliting 
exit edge to preserve LCSSA.

Dan Gohman fa3eeeedc0 Mark the SSE and MMX load instructions that 
X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.

Chris Lattner 04e3d20a51 Increase the macro id cache to look up several recent entries, not just the last one. 
This is important in insane cases like the one dannyb sent me recently:

#define F0(a) void a(){}
#define F1(a) F0(a##0) F0(a##1) F0(a##2) F0(a##3) F0(a##4) F0(a##5) F0(a##6) F0(a##7)
#define F2(a) F1(a##0) F1(a##1) F1(a##2) F1(a##3) F1(a##4) F1(a##5) F1(a##6) F1(a##7)
#define F3(a) F2(a##0) F2(a##1) F2(a##2) F2(a##3) F2(a##4) F2(a##5) F2(a##6) F2(a##7)
#define F4(a) F3(a##0) F3(a##1) F3(a##2) F3(a##3) F3(a##4) F3(a##5) F3(a##6) F3(a##7)
#define F5(a) F4(a##0) F4(a##1) F4(a##2) F4(a##3) F4(a##4) F4(a##5) F4(a##6) F4(a##7)

Evan Cheng c5549fc3a0 Instead of adding copyfromreg's to handle physical definitions. Now isel can 
simply specify them as results and let scheduledag handle them. That
is, instead of
SDOperand Flag = DAG.getTargetNode(Opc, MVT::i32, MVT::Flag, ...)
SDOperand Result = DAG.getCopyFromReg(Chain, X86::EAX, MVT::i32, Flag)

Just write:
SDOperand Result = DAG.getTargetNode(Opc, MVT::i32, MVT::i32, ...)

And let scheduledag emit the move from X86::EAX to a virtual register.
