9f622b5659 Re-defined valno is always valno even for partial re-def's.

776d3dcfb4 Fix PR7096. When a block containing multiple defs is tail duplicated, the 
SSAUpdater for the value from the first def may see uses of undefined values,
because the later defs will not have been updated yet.

e74d980a02 make simplifycfg insert an llvm.trap before the 'unreachable' it introduces 
when it detects undefined behavior.  llvm.trap generally codegens into some
thing really small (e.g. a 2 byte ud2 instruction on x86) and debugging this
sort of thing is "nontrivial".  For example, we now compile:

void foo() { *(int*)0 = 42; }

into:

_foo:
	pushl	%ebp
	movl	%esp, %ebp
	ud2

Some may even claim that this is a security hole, though that seems dubious
to me.  This addresses rdar://7958343 - Optimizing away null dereference 
potentially allows arbitrary code execution

0b442d35da Teach instcombine to transform a bitcast/(zext|trunc)/bitcast sequence 
with a vector input and output into a shuffle vector.  This sort of 
sequence happens when the input code stores with one type and reloads
with another type and then SROA promotes to i96 integers, which make
everyone sad.

This fixes rdar://7896024

4ca74b9c6c When pruning candidate formulae out of an LSRUse, update the 
LSRUse's Regs set after all pruning is done, rather than trying
to do it on the fly, which can produce an incomplete result.

This fixes a case where heuristic pruning was stripping all
formulae from a use, which led the solver to enter an infinite
loop.

Also, add a few asserts to diagnose this kind of situation.

1ee37ac5d4 Fix PR 7087, and probably other things, by extending 
getConstantFP to accept the two supported long double
target types.  This was not the original intent, but
there are other places that assume this works and it's
easy enough to do.
