e04cec0ecf Significant improvements to the logic for merging live intervals. This code can't 
just use LI::MergeValueAsValue, as its behavior in the presence of overlapping ranges
isn't what StrongPHIElimination wants.

743922ea75 Fold immediates into X86 shifts with fast isel. This generates: 
sarl    $3, %ecx

instead of:

movl    $3, %ecx
sarl    %cl, %edx

This shrinks fast isel 176.gcc by about 2000 instructions (.3%)
