mips.h (STARTING_FRAME_OFFSET): Remove rtl profiling code.

gcc/
	* config/mips/mips.h (STARTING_FRAME_OFFSET): Remove rtl
	profiling code.
	* config/mips/mips.c (mips_frame_info): Give num_gp and num_fp type
	"unsigned int" rather than "int" and put them with the other
	register-related fields.  Put expanded comments above fields
	rather than to their right.
	(mips16e_mask_registers): Replace the GP_REG_SIZE_PTR argument
	with a NUM_REGS_PTR argument.
	(mips16e_save_restore_pattern_p): Update accordingly.
	(compute_frame_size): Clarify frame diagram.  Rewrite.
