This patch extends the other mode_supports* function to take an optional
second argument to specificy particular reload register class, and it defaults
to REG_RELOAD_ANY which says some reload register supports the feature.

I have built bootstrap compilers with the first 4 patches including this patch
on both big and little endian power8 systems.  There were no regressions.

2018-03-21  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/rs6000.c (mode_supports_pre_incdec_p): Add
	additional argument to specify the reload register class to use,
	defaulting to RELOAD_REG_ANY.
	(mode_supports_pre_modify_p): Likewise.
	(mode_supports_dq_form): Likewise.
