i386: Add costs for integer<->float conversions

Extend ix86_rtx_costs to cost FLOAT, UNSIGNED_FLOAT, FIX, and UNSIGNED_FIX.
There are many variants of integer<->float conversions and it seems
meaningful to start with the typical scalar and vector ones. On modern CPUs the
variants differs by at most 1 cycle.

gcc/ChangeLog:

	* config/i386/i386.cc (ix86_rtx_costs): Cost FLOAT, UNSIGNED_FLOAT,
	FIX, UNSIGNED_FIX.
	* config/i386/i386.h (struct processor_costs): Add
	cvtsi2ss, cvtss2si, cvtpi2ps, cvtps2pi.
	* config/i386/x86-tune-costs.h (struct processor_costs): Update tables.
