Correct errors in sparc SImode popcount/clz patterns when 64-bit.
* config/sparc/sparc.md (popcount<mode>2, clz<mode>2): Split up into...
(popcountdi2, popcountsi2, clzdi2, clzsi2): Explicit expanders, in the
SI mode 64-bit code gen case explicitly zero-extend and truncate.
(*popcount<mode>_sp64): Split up into...
(*popcountdi_sp64, *popcountsi_64): Explicit instantiations, and in the
SImode case use truncate.
(*clzsi_sp64): Rewrite to use truncate, and let the expander emit the
subtract so the compiler can optimize it.
(SIDI): Remove unused mode iterator.
