Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

Sanjay Patel 764ae8bd72 [x86] add folds for FP logic with vector zeros
The 'or' case shows up in copysign. The copysign code also had 
redundant checking for a scalar zero operand with 'and', so I 
removed that. 

I'm not sure how to test vector 'and', 'andn', and 'xor' yet, 
but it seems better to just include all of the logic ops since
we're fixing 'or' anyway.

Sanjay Patel 0b36337d61 [x86] fix FCOPYSIGN lowering to create constants instead of ConstantPool loads
This is similar to:
https://reviews.llvm.org/rL279958

By not prematurely lowering to loads, we should be able to more easily eliminate
the 'or' with zero instructions seen in copysign-constant-magnitude.ll.

We should also be able to extend this code to handle vectors.

Sanjay Patel db3438abcb [x86] split up tests, regenerate checks
Note that we fail to eliminate 'or' with 0!

Craig Topper 9bd6241106 [X86] Remove the Fv packed logical operation alias instructions. Replace them with patterns to the regular instructions.
This enables execution domain fixing which is why the tests changed.

Justin Bogner 3135ba9b38 AsmPrinter: Use emitGlobalConstantFP to emit elements of constant data
It's strange to duplicate the logic for emitting FP values into
emitGlobalConstantDataSequential, and it's even stranger that we end
up printing the verbose assembly comments differently between the two
paths. Just call into emitGlobalConstantFP rather than crudely
duplicating its logic.

Ahmed Bougacha aa2d290997 [X86] Teach FCOPYSIGN lowering to recognize constant magnitudes.
For code like:
    float foo(float x) { return copysign(1.0, x); }
We used to generate:
    andps  <-0.000000e+00,0,0,0>, %xmm0
    movss  <1.000000e+00>, %xmm1
    andps  <nan>, %xmm1
    orps   %xmm0, %xmm1
Basically doing an abs(1.0f) in the two middle instructions.

We now generate:
    andps  <-0.000000e+00,0,0,0>, %xmm0
    orps   <1.000000e+00,0,0,0>, %xmm0

Builds on cleanups r223415, r223542.
