[SPARC] Fix miscompilation of ada/g-calend.adb at -O2

[Eric Botcazou]

There is now a tail call in Time_Of with lot of 64-bit quantities around, 
including arguments, and this exposes an oversight in adddi3_insn_sp32.

Bootstrapped/regtested on SPARC/Solaris, applied on mainline and 4.7 branch.

* config/sparc/sparc.md (adddi3_insn_sp32): Add earlyclobber.
