	Tweak directives in GCC tests for msp430-elf

	gcc/ChangeLog:

	* doc/sourcebuild.texi: Document check_effective_target_int_eq_float
	and check_effective_target_ptr_eq_long.

	gcc/testsuite/ChangeLog:

	* c-c++-common/pr41779.c: Require int_eq_float for dg-warning tests.
	* c-c++-common/pr57371-2.c: XFAIL optimized dump scan when
	sizeof (float) != sizeof (int).
	* gcc.dg/pr84670-4.c: Require ptr_eq_long.
	* gcc.dg/pr85859.c: Likewise.
	* gcc.dg/Wno-frame-address.c: Skip for msp430-elf.

	* gcc.dg/tree-ssa/20040204-1.c: Likewise.
	* gcc.dg/compat/struct-by-value-16a_x.c: Build at -O1 for msp430
	so it fits.
	* gcc.dg/lto/20091013-1_0.c: Require ptr_eq_long.
	* gcc.dg/lto/20091013-1_1.c: Remove xfail-if for when
	sizeof(void *) != sizeof(long).
	* gcc.dg/lto/20091013-1_2.c: Likewise.
	* gcc.dg/tree-ssa/loop-1.c: Fix expected dg-final behaviour for msp430.
	* gcc.dg/tree-ssa/gen-vect-25.c: Likewise.
	* gcc.dg/tree-ssa/gen-vect-11.c: Likewise.
	* gcc.dg/tree-ssa/loop-35.c: Likewise.
