Changes in directory llvm/lib/Target/Alpha:

AlphaISelPattern.cpp updated: 1.135 -> 1.136
---
Log message:

So, it turns out I forgot that one valid way of restoring GP after a call
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.
