033d31165d merge the linux cpool/jtbl pic tests into pic.ll and convert to filecheck. 
Change the picbase symbol on non-darwin systems from ".Lllvm$4.$piclabel" to
".L4$pb".  The actual name doesn't matter and the darwin name is shorter.

6c89da7027 Define proper subreg sets for arm - this should fix bunch of subtle problems 
with subreg - superreg mapping and also fix PR4965.

f437e68058 Add -mattr=+sse2 to the -march=x86 version of this test. Without 
sse, this code falls back to SelectionDAG isel which uses an x87
instruction, which is fine, but not what this test is testing for.

input filename so that opt doesn't print the input filename in the

strings in the input filename.

74a3231de4 Follow up to 81494. When the folded reload is narrowed to a 32-bit load then change the destination register to a 32-bit one or add a sub-register index.

3cad6283b8 It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not 
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

e819cfbc71 change selectiondag to add the sign extended versions of immediate operands 
to instructions instead of zero extended ones.  This makes the asmprinter
print signed values more consistently.  This apparently only really affects
the X86 backend.

b2fcd070e2 fix PR4767, a crash because fp stackifier visited blocks in 
depth first order, so it wouldn't process unreachable blocks.
When compiling at -O0, late dead block elimination isn't done
and the bad instructions got to isel.

2512a42548 Fix a thinko: When lowering fneg with xor, bitcast the operands 
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.

7f20002993 Stabilize the order of live intervals in the priority_queue used by the 
linear scan reg alloc.  This fixes a problem I ran into where extracting
a function from a larger file caused the generated code to change (masking
the problem I was trying to debug) because the allocator behaved differently.

This changes the results for two X86 regression checks.  stack-color-with-reg
is improved, with one less instruction, but pr3495 is worse, with one more
copy.  As far as I can tell, these tests were just getting lucky or unlucky,
so I've changed the expected results.
