forming [disp+rip] encoding.  Rewrite the SIB byte decision logic
to be actually understandable.

into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

'%al,' it would report 'al,' as the token.  Now it
correctly reports '%al'.

Thanks to Kristaps Straupe for noticing the bug.

only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.

Do not emit callseq instructions around sibcalls. This eliminated some unnecessary stack adjustments.

Instruction selection for X86 now can choose an instruction
sequence that will fit any address of any symbol, no matter
the pointer width. X86-64 uses a mov+call-via-reg sequence
for this.
