sframe: fix the defined SFRAME_FRE_TYPE_*_LIMIT constants

Browse Source 
An earlier commit 3f107464 defined the SFRAME_FRE_TYPE_*_LIMIT
constants.  These constants are used (by gas and libsframe) to pick an
SFrame FRE type based on the function size.  Those constants, however,
were buggy, causing the generated SFrame sections to be bloated as
SFRAME_FRE_TYPE_ADDR2/SFRAME_FRE_TYPE_ADDR4 got chosen more often than
necessary.

gas/
	* sframe-opt.c (sframe_estimate_size_before_relax): Use
	typecast.
	(sframe_convert_frag): Likewise.

libsframe/
	* sframe.c (sframe_calc_fre_type): Use a more appropriate type
	for argument.  Adjust the check for SFRAME_FRE_TYPE_ADDR4_LIMIT
	to keep it warning-free but meaningful.

include/
	* sframe-api.h (sframe_calc_fre_type): Use a more appropriate
	type for the argument.
	* sframe.h (SFRAME_FRE_TYPE_ADDR1_LIMIT): Correct the constant.
	(SFRAME_FRE_TYPE_ADDR2_LIMIT): Likewise.
	(SFRAME_FRE_TYPE_ADDR4_LIMIT): Likewise.
