	internal: introduced opt-pentium-*.c from new scheduler. speeds
		up Pentium 28high from 1.33 million to 1.24 million.
	internal: transposed sqtab into the most cache-friendly order.
	internal: miscellaneous pentium improvements, including sensible
		use of temporary space, sensible order of functions for
		wimpy i-cache. now under 1.14 million.
20011014
	internal: miscellaneous ppro improvements, including some
		contributions from new scheduler. speeds up Pentium III
		28high from 0.93 million to 0.84 million. also speeds up
		Athlon from 0.75 million to 0.69 million, and P4 from
		1.09 million to 0.98 million.
	internal: new opt-sparc-*.c from new scheduler. a few percent.
	internal: added mftb for PowerPC timings.
	internal: added opt-powerpc.c.
20011015
	internal: moved local statics to global in opt-powerpc.c.
	internal: new opt-powerpc-*.c from new scheduler.
20011016
	internal: introduced floatasm.h, so that powerpc will compile on
		other platforms.
	internal: more scheduling in opt-sparc.c, particularly in
		ecdouble and p_sqrt. ecdouble now uses tmp. 28high down
		to 0.80 million.
20011017
	internal: changed constants to const double.
	internal: revised opt-powerpc-*.c, now that I understand the
		PowerPC's inability to keep the FPU busy every cycle.
	internal: put constants inside a struct for powerpc, to work
		around gcc alignment bug on MacOS X. grrrr.
	internal: added long long pad to constants and spills for
		powerpc, and added explicit zero intializers, to work
		around gcc alignment bug on AIX.
