g++.dg/opt/strength-reduce.C: Replace 0x7fffffff with __INT_MAX__ so that
the test can be compiled by toolchains targeted at 16-bit processors.

* gcc.dg/20040625-1.c: Use long constants rather than integers when
performing arithmetic that will overflow 16-bits.

* gcc.dg/i386-sse-8.c: Expect this test to fail for the	xstormy16.
It does not support 128-bit vector operations.

* gcc.dg/ultrasp4.c: Replace all occurrences of the type 'long'	with the
macro PTR_TYPE.  Define this macro to an integer type suitable for
holding a pointer.

* gcc.dg/compat/struct-align-1_x.c: Use shorter integers if the target
is a 16-bit processor.

* gcc.dg/cpp/if-2.c: Expect a different warning message from 16-bit
targets where the character constant will be too long.

* g++.dg/opt/asm1.C: Expect this test to fail on the xstormy16 where
the double will not be directly addressable.
