re PR target/62631 (gcc.dg/tree-ssa/ivopts-lt-2.c FAILs)
PR target/62631
* config/sparc/sparc.h (TARGET_HARD_MUL): Remove TARGET_V8PLUS.
(TARGET_HARD_MUL32): Rewrite based on TARGET_HARD_MUL.
* config/sparc/sparc.c (sparc_rtx_costs) <MULT>: Return costs based on
int_mulX for integers in 64-bit mode if TARGET_HARD_MUL is not set.
