Patch that removes the crash
This patch fixes the problem by tolerating IPA ESRA's leaving removed
PARM_DECLs alone, instead of replacing them with VAR_DECLs. I would rather we
used a VAR_DECL instead, because I'm concerned about other places that
distinguish between PARM_DECLs and VAR_DECLs, at least when it comes to
handling their default defs. I haven't looked into this possibility yet,
though; it might be that other pieces of the compiler rely on the decls
remaining as PARM_DECLs for other purposes.
