Mon P Wang bc65ca8de5 Added option to enable generating less precise mad (multiply addition)
for those architectures that support the instruction.

Dan Gohman 654c98c4f3 The last use in a block that doesn't have successors
(return or unreachable) is a kill.

Sebastian Redl 48fe63526e Fix the Win32 VS2008 build:
- Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

Dale Johannesen 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.

Dan Gohman 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.

Dale Johannesen 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.

Nate Begeman 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.

Chris Lattner 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.

Chris Lattner b7e64ac3ac LSR shouldn't ever try to hack on integer IV's larger than 64-bits. Right now

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.
