778a5e27b0 Make use of vector load and store operations to implement memcpy, memmove, and memset. Currently only X86 target is taking advantage of these.

f8b1257d2e Add a quick and dirty "loop aligner pass". x86 uses it to align its loops to 16-byte boundaries.

295ae42ede Don't track max alignment during stack object allocations since they can be deleted later. Let PEI compute it.

f2a0e6c176 Reorder a field to reduce the size of StackObject. Note that this 
may require a clean rebuild on leopard. :(

93f4f5970c move this field back. Moving the field causes miscompilations (!) of voronoi and others.

1ce075bcaa move MachineFrameInfo::CreateFixedObject out of line, give MachineFrameInfo 
a reference to TargetFrameInfo.  Rearrange order of fields in StackObject to
save a word.

f20828226e Add a isImmutable bit to StackObject. Fixed stack objects are immutable (in the function) unless specified otherwise.

aecebc076b 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.
