Per review feedback: Only perform
(srl x, (trunc (and y, c))) -> (srl x, (and (trunc y), c))
etc. when both "trunc" and "and" have single uses.

Change the calling convention used when tail call optimization is enabled from CC_X86_32_TailCall to CC_X86_32_FastCC.

add_partially_linked_object: Replaced nonexistent MESSAGE option in
add_custom_command with COMMENT. It was forcing unconditional command
execution.

Add helper function to get a 32-bit floating point constant. No functionality change.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56418 91177308-0d34-0410-b5e6-96231b3b80d8

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%)

Factor out code into HandleVirtRegDef, for consistency with
Handle{Virt,Phys}Reg{Def,Use}. Remove a redundant check
for register zero, and redundant checks for isPhysicalRegister.

Instead of building a list and sorting it just to find a maximum element,
compute the maximum element directly.

Fetch the starting index of the block when assigning intervals.  This gets live-in indices
correct in the presence of things like EH labels.
