Fixes to x86 register promotion and load hoisting.

Fixed a check to ensure that the mvzxb source register can be byte
accessed, not the destination reg.

Disabled branch fusion for x86 since code generation for that is
unimplemented.

Changed regId mask for x86 to allow proper masking of double registers.

Also added more output to the disassembler.
