  -----------
  [MemoryBuiltins] Add field for alignment argument [NFC]

There are a few places where the alignment argument for AlignedAllocLike functions was previously hardcoded. This patch adds an getAllocAlignment function and a change to the MemoryBuiltin table to allow alignment arguments to be found generically.

This will shortly allow alignment inference on operator new's with align_val params and an extension to Attributor's HeapToStack.  The former will follow shortly - I split Bryce's patch for purpose of having the large change be NFC.  The later will be reviewed separately.

  Log Message:
  -----------
  [instcombine] Add align return attributes for operator new(..., align_val)

(Split from original patch to separate non-NFC part and add coverage.  I typoed when adding the new test, so this change includes the typo fix to let libfunc recongize the signature.  Didn't figure it was worth another separate commit.)
