pa.c (pa_output_call): Load descriptor address to register %r22.

	* config/pa/pa.c (pa_output_call): Load descriptor address to register
	%r22.  Load function address before global pointer.
	(pa_attr_length_indirect_call): Adjust length of inline versions of
	$$dyncall.
	(pa_output_indirect_call): Remove fast inline version of $$dyncall
	before normal cases.  Update inline $$dyncall sequences to preserve
	function descriptor address in register %r22.
	(TRAMPOLINE_CODE_SIZE): Adjust.
	(pa_asm_trampoline_template): Revise 32-bit trampoline.  Don't assume
	register %r22 contains trampoline address.
	(pa_trampoline_init): Adjust offsets.
	(pa_trampoline_adjust_address): Likewise.
	* config/pa/pa.h (TRAMPOLINE_SIZE): Adjust 32-bit size.
