[SPARC] Minor tweaks

[Eric Botcazou]

The correct test for the pointer size in sparc_emit_probe_stack_range is 
TARGET_ARCH64 instead of TARGET_64BIT.  The patch also adds predicates to the 
3rd argument of ctrapsi4 and ctrapdi4.

Tested on SPARC/Solaris, applied on the mainline.


2013-03-23  Eric Botcazou  <ebotca...@adacore.com>

        * config/sparc/sparc.c (sparc_emit_probe_stack_range): Fix small
        inaccuracy in the probing code.

        * config/sparc/sparc.md (ctrapsi4): Add predicate for operand #3.
        (ctrapdi4): Likewise.
