other things.

properly sign extending the top of the result of a 64-bit shift right by
a constant > 32.

27b4c23b80 Fixed version of optimized integer divide is now fixed. Calculate the 
quotient, not the remainder.  Also, make sure to remove the old div operand
from the ExprMap and let SelectExpr insert the new one.

439b444cad Rename canUseAsImmediateForOpcode to getImmediateForOpcode to better 
indicate that it is not a boolean function.
Properly emit the pseudo instruction for conditional branch, so that we
  can fix up conditional branches whose displacements are too large.
Reserve the right amount of opcode space for said pseudo instructions.

d860aa62ac Make sure that arg regs used by the call instruction are marked as such, so 
that regalloc doesn't cleverly reuse early arg regs loading later arg regs.
This fixes almost all outstanding failures in the pattern isel.

6e02e6842a fix SREM/UREM, which gave incorrect results for x%y if x was zero. This is 
an ugly hack, but it seems to work. I should fix this properly and add a test
as well.
