gcc.dg/analyzer/allocation-size-1..5.c: Fix for 32-bit newlib targets

See gcc/config/newlib-stdint.h, where targets that have
LONG_TYPE_SIZE == 32, get INT32_TYPE defined to "long int".
INT32_TYPE ends up in the target int32_t.

Thus the tests failed for 32-bit newlib targets due to related
warning messages being matched to "aka int" where the emitted
message for these targets have "aka long int".

Tested cris-elf, committed as obvious.

gcc/testsuite:
	* gcc.dg/analyzer/allocation-size-1.c,
	gcc.dg/analyzer/allocation-size-2.c,
	gcc.dg/analyzer/allocation-size-3.c,
	gcc.dg/analyzer/allocation-size-4.c,
	gcc.dg/analyzer/allocation-size-5.c: Handle int32_t being "long int".
