This switches the picbase load and reload patterns to use the 'P' mode
iterator instead of writing an SI and DI pattern for each (and deletes the
old patterns).  No functional change intended.

Tested on powerpc-darwin9, powerpc64-linux-gnu,
applied to mainline
thanks

gcc/ChangeLog:

2019-09-24  Iain Sandoe  <iain@sandoe.co.uk>

	* config/rs6000/rs6000.md (load_macho_picbase_<mode>): New, using
	the 'P' mode iterator, replacing the (removed) SI and DI variants.
	(reload_macho_picbase_<mode>): Likewise.
