Log:
rs6000: Remove TARGET_FPRS

Since rs6000 no longer supports SPE, TARGET_FPRS now always is true.

This makes TARGET_{SF,DF}_SPE always false.  Many patterns in spe.md
can now be deleted; which makes it possible to merge e.g. negdd2 with
*negdd2_fpr.

Finally, e500.h is deleted (it isn't used).


	* config/rs6000/darwin.md: Replace TARGET_FPRS by 1 and simplify.
	* config/rs6000/dfp.md: Ditto.
	(negdd2, *negdd2_fpr): Merge.
	(absdd2, *absdd2_fpr): Merge.
	(negtd2, *negtd2_fpr): Merge.
	(abstd2, *abstd2_fpr): Merge.
	* config/rs6000/e500.h: Delete file.
	* config/rs6000/predicates.md (rs6000_cbranch_operator): Replace
	TARGET_FPRS by 1 and simplify.
	* config/rs6000/rs6000-c.c: Ditto.
	* config/rs6000/rs6000.c: Ditto.  Also replace TARGET_SF_SPE and
	TARGET_DF_SPE by 0.
	* config/rs6000/rs6000.h: Ditto.  Delete TARGET_SF_SPE and
	TARGET_DF_SPE.
	* config/rs6000/rs6000.md: Ditto.
	(floatdidf2, *floatdidf2_fpr): Merge.
	(move_from_CR_gt_bit): Delete.
	* config/rs6000/spe.md: Replace TARGET_FPRS by 1 and simplify.
	(E500_CR_IOR_COMPARE): Delete.
	(All patterns that require !TARGET_FPRS): Delete.
	* config/rs6000/vsx.md: Replace TARGET_FPRS by 1 and simplify.
