1f67ce4aa3 Clear the cached cost when removing a function in 
the inliner; prevents nondeterministic behavior
when the same address is reallocated.
Don't build call graph nodes for debug intrinsic calls;
they're useless, and there were typically a lot of them.

3751f564e3 Add a liveness analysis pass for LLVM IR values. This computes 
the set of blocks in which values are used, the set in which
values are live-through, and the set in which values are
killed. For the live-through and killed sets, conservative
approximations are used.

f4978e2094 This pass keeps a map of Instructions to Rank numbers, 
and was deleting Instructions without clearing the
corresponding map entry.  This led to nondeterministic
behavior if the same address got allocated to another
Instruction within a short time.

7cee81703d Add support to tablegen for naming the nodes themselves, not just the operands, 
in selectiondag patterns.  This is required for the upcoming shuffle_vector rewrite,
and as it turns out, cleans up a hack in the Alpha instruction info.

ff81ebf758 Disable the "call to immediate" optimization on x86-64. It is 
not safe in general because the immediate could be an arbitrary
value that does not fit in a 32-bit pcrel displacement.  
Conservatively fall back to loading the value into a register
and calling through it.

We still do the optzn on X86-32.

b7e64ac3ac LSR shouldn't ever try to hack on integer IV's larger than 64-bits. Right now 
it is not APInt clean, but even when it is it needs to be evaluated carefully

0b18e59336 Fix codegen to compute the size of an allocation by multiplying the 
size by the array amount as an i32 value instead of promoting from
i32 to i64 then doing the multiply.  Not doing this broke wrap-around
assumptions that the optimizers (validly) made.  The ultimate real
fix for this is to introduce i64 version of alloca and remove mallocinst.
