rs6000: Fix "missing mode" on UNSPEC_TOCSLOT

Currently gen* warn about a missing mode on an UNSPEC_TOCSLOT unspec in
some call patterns.  Those unspecs are created from rs6000.c, with Pmode
always.  This patch fixes the patterns to say :P as well.


	* config/rs6000/rs6000.md (*call_indirect_aix<mode>,
	*call_value_indirect_aix<mode>, *call_indirect_elfv2<mode>,
	*call_value_indirect_elfv2<mode>): Add correct mode to the unspec.
