JF Bastien 24e01d0990 WebAssembly: fix build breakage.
Summary:
processFunctionBeforeCalleeSavedScan was renamed to determineCalleeSaves and now takes a BitVector parameter as of rL242165, reviewed in http://reviews.llvm.org/D10909

WebAssembly is still marked as experimental and therefore doesn't build by default. It does, however, grep by default! I notice that processFunctionBeforeCalleeSavedScan is still mentioned in a few comments and error messages, which I also fixed.

; Leaf function which uses all callee-saved registers and allocates >= 256 bytes
; on the stack this will cause determineCalleeSaves() to spill LR as an
; additional scratch register.

; This is a crash-only regression test for rdar://15124582.
