Fix PR target/107248
This is the infamous PR rtl-optimization/38644 rearing its ugly head for
leaf functions on SPARC more than a decade later... Richard E.'s generic

PR target/107248
* config/sparc/sparc.cc (sparc_expand_prologue): Emit a frame
blockage for leaf functions.
(sparc_flat_expand_prologue): Emit frame instead of full blockage.
(sparc_expand_epilogue): Emit a frame blockage for leaf functions.
(sparc_flat_expand_epilogue): Emit frame instead of full blockage.
