df2e425f2a Add a new option to indicate we want the code generator to emit code quickly, 
not spending tons of time microoptimizing it.  This is useful for an -O0
style of build.

ae232e7a10 Add the necessary support to the ISel to allow targets to codegen the new 
alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

14b0529532 Add support alignment of allocation instructions. 
Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

66c5fd6c53 When a function takes a variable number of pointer arguments, with a zero 
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

405e3ecb56 Invert the TargetLowering flag that controls divide by consant expansion. 
Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.

Remove now dead code in the x86 backend.

5e93fbe68c Add a new flag for targets where setjmp/longjmp saves/restores the signal mask, 
and _setjmp/_longjmp should be used instead (for llvm.setjmp/llvm.longjmp).

09f00b1295 Make this slightly more efficient by pushing actual type information down 
into the evaluator.  This shrinks a release build of instcombine's text
section from 216363 to 215975 bytes (on PPC).

225e8dd2f5 Split SimpleConstantVal up into its components, so each Constant subclass gets 
a different enum value.  This allows 'classof' for these to be really simple,
not needing to call getType() anymore.

This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
