Lift register and condition code enums out into their own file.

Lift the enums out of IceInstX8632.h and IceTargetLoweringX8632.h.
This will later allow the assembler to share the enum values and
use them as encodings where appropriate. E.g., to avoid having a separate
enum in:
https://codereview.chromium.org/476323004/diff/680001/src/assembler_constants_ia32.h

The "all registers" enum is retained, but separate GPRRegister and
XmmRegister enums are created with tags "Encoded_Reg_foo" to represent
the encoded value of register "foo". Functions are added to convert
from the "all registers" namespace to the encoded ones.

Re-order the BrCond so that they match the encoding according to
the "Instruction Subcode" in B.1 of the Intel Manuals.
