4ac7a0ca8f reject patterns that have dead named arguments in the input pattern 
this is tidier and can find bugs.

6d9f86b773 remove a bunch of dead named arguments in input patterns, 
though some look dubious afaict, these are all ok.

967d54ae04 reject patterns that mention a name in the destination pattern 
but not in the input.  Previously, this would trigger an abort
late in the isel logic.

be5ad7dce2 fix a type mismatch in this pattern, where we were using an i64 imm in a 
place where an i32 imm was required, the old isel just got lucky.

This fixes CodeGen/X86/x86-64-and-mask.ll

27e998984c the cell backend is making all sorts of unsafe and incorrect assumptions

3e22f2d489 add a new Push2 opcode for targets (like cellspu) which have 
ridiculously ginormous patterns and need more than one byte
of displacement for encodings.  This fixes CellSPU/fdiv.ll.
SPU is still doing something else ridiculous though.

6e5dfd4bf5 Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

20df2420f7 Change ComplexPattern handling to push the node being matched as 
well as the operands produced when the pattern is matched.  This
allows CheckSame to work correctly when matching replicated 
names involving ComplexPatterns.  This fixes a bunch of MSP430 
failures, we're down to 13 failures, two of which are
due to a sched bug.

4642ad3af1 Updated version of r96634 (which was reverted due to failing 176.gcc and 
126.gcc nightly tests. These failures uncovered latent bugs that machine DCE
could remove one half of a stack adjust down/up pair, causing PEI to assert.
This update fixes that, and the tests now pass.

0e488b3d1c Canonicalize ConstantInts to the right operand of commutative 
operators.

The test difference is just due to the multiplication operands
being commuted (and thus requiring a more elaborate match). In
optimized code, that expression would be folded.

9265275a9a Mark the return address stack slot as mutable when moving the return address 
during a tail call. A parameter might overwrite this stack slot during the tail
call. 

The sequence during a tail call is:
1.) load return address to temp reg
2.) move parameters (might involve storing to return address stack slot)
3.) store return address to new location from temp reg

If the stack location is marked immutable CodeGen can colocate load (1) with the
store (3).

This fixes bug 6225.
