Subject: testsuite patches (12/14): Add predicates to tests that depend on integer size

Tested for avr with --target_board=atmega128-sim and native oni686-pc-linuc-gnu.

2013-07-17  Joern Rennecke <joern.rennecke@embecosm.com>

	* c-c++-common/simulate-thread/bitfields-2.c: Run test only for
	target { ! int16 }.
	* gcc.dg/tree-ssa/pr54245.c: Do slsr scan only for target { ! int16 }.
	* gcc.dg/tree-ssa/slsr-1.c: Adjust multiplicators to scan for for
	target { int16 }.  Restrict existing tests to target { int32 }
	where appropriate.
	* gcc.dg/tree-ssa/slsr-2.c, gcc.dg/tree-ssa/slsr-27.c: Likewise.
	* gcc.dg/tree-ssa/slsr-28.c, gcc.dg/tree-ssa/slsr-29.c: Likewise.
	* gcc.dg/tree-ssa/slsr-3.c, gcc.dg/tree-ssa/ssa-ccp-23.c: Likewise.
	* lib/target-supports.exp (check_effective_target_int32): New proc.
