Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates.
...
llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored. The others remain unchanged.

Add a neat little two's complement hack for x86.
...
On x86 we can't encode an immediate LHS of a sub directly. If the RHS comes from a XOR with a constant we can
fold the negation into the xor and add one to the immediate of the sub. Then we can turn the sub into an add,
which can be commuted and encoded efficiently.
This code is generated for __builtin_clz and friends.
