{40x.md,603.md,6xx.md,7450.md,7xx.md,mpc.md, [...]: Change mult_compare to imul_compare.
* config/rs6000/{40x.md,603.md,6xx.md,7450.md,7xx.md,mpc.md,
power4.md,rios1.md,rios2.md,rs64.md}: Change mult_compare to
imul_compare. Add lmul_compare.
* config/rs6000/power4.md: Bump some latencies. Model extra cycle
in second pair of dispatch slots. Model stores more accurately.
Tweak multiply model. Add bypasses for CR instructions dependent
on complicated compares.
* config/rs6000/rs6000.md (mulsi3): Name imul_compare patterns.
(muldi3): Add lmul_compare patterns.
* config/rs6000/rs6000.c (rs6000_variable_issue): Move FPLOAD_UX
and FPSTORE_UX to split instructions and add COMPARE,
DELAYED_COMPARE, IMUL_COMPARE, LMUL_COMPARE, IDIV, LDIV.
(rs6000_adjust_cost): Add IMUL_COMPARE and LMUL_COMPARE.
(rs6000_rtx_costs): Separate POWER4 multiply case.
