  -----------
  Attributes: add a new allocalign attribute

This will let us start moving away from hard-coded attributes in
MemoryBuiltins.cpp and put the knowledge about various attribute
functions in the compilers that emit those calls where it probably
belongs.

  BuildLibCalls: add allocalign attributes for memalign and aligned_alloc

This gets us close to being able to remove a column from the table in
MemoryBuiltins.cpp.

  getAllocAlignment: respect allocalign attribute if present

As with allocsize(), we prefer the table data to attributes.
