rounding the stack frame to a multiple of stack alignment.

llvm-svn: 33504

PEI is now responsible for adding MaxCallFrameSize to frame size and align the stack. Each target can further adjust the frame size if necessary.

llvm-svn: 33460

llvm-svn: 33396

We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

Put this change back in after testing from Reid proved its innocence.  getSpillSize now returns value in bits

Back out change to divide getSpillSize by 8 until I figure out why it breaks x86, which has register sizes in bits.
