[SPARC]: Audit inline asm. 

Check all inline asms for common bugs and things that prevent
gcc-3.3 builds from working, in particular:
1) Missing memory or cc clobbers.
2) Do not clobber registers explicitly assigned to input
   variables.
3) extern __inline__ --> static inline.

Also try to make the formatting more consistent so that
future audits are a bit easier.

Based upon work done by Keith W. and Meelis Roos.
