Charles Davis a90f7ca591 Warn about using the new force_align_arg_pointer attribute on a function
pointer. If you don't like the new warning, you can turn it off with
-Wno-force-align-arg-pointer.

Charles Davis bbc0aa5166 Add support for the force_align_arg_pointer attribute. This is an x86-specific
attribute, so it uses Anton's new target-specific attribute support. It's
supposed to ensure that the stack is 16-byte aligned, but since necessary
support is lacking from LLVM, this is a no-op for now.

Anton Korobeynikov 55bcea1e65 Generalize target weirdness handling having proper layering in mind:
1. Add helper class for sema checks for target attributes
 2. Add helper class for codegen of target attributes

As a proof-of-concept - implement msp430's 'interrupt' attribute.
