Move the code that adds the DeadMachineInstructionElimPass from
target-independent code to target-specific code. This prevents it
from running on targets that aren't using fast-isel.

In addition to saving compile time, this addresses the problem
that not all targets are prepared for it. In order to use this
pass, all instructions must declare all their fixed uses and
defs of physical registers.

fix PR2953, an off-by-one error handling formatted i/o. 
Thanks to Török Edwin for the awesome reduced testcase.

Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized
a memset using 16-byte XMM stores, but where the stack realignment code
didn't work.  Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.

This is part of PR2888

Fix incorrect testing for the end of the both strings in CStrInCStrNoCase.  This could cause a read-out-of-bounds error if s2 is smaller than s1.

Disallow the construction of SCEVs with could-not-compute operands. Catch CNCs
returned by BinomialCoefficient and don't try to operate with them. This
replaces the previous fix for PR2857.

remove v[if]cmp functionality from the 2.4 release.  These instructions will be removed or substantially changes in mainline after the 2.4 release and we don't want to have to support these for backwards compatibility purposes.  Patch by Chris.

Improve the description on the getelementptr instruction. It should now better
define what the instruction does. This also makes it clear that getelementptr
can index into a vector type.

Change CALLSEQ_BEGIN and CALLSEQ_END to take TargetConstant's as
parameters instead of raw Constants.  This prevents the constants from
being selected by the isel pass, fixing PR2735.

Fix PR2697 by rewriting the '(X / pos) op neg' logic.  This also changes a couple other cases for clarity, but shouldn't affect correctness.

since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a
load-and-convert of int 0.  Fixes
