[gcc r13-1409] Use fixed-width types in allocation size tests

[gcc r13-1409] Use fixed-width types in allocation size tests

[Tim Lange]

https://gcc.gnu.org/g:b5c3dd3df381896b09fa76b52cd7a49b9b24afb3

commit r13-1409-gb5c3dd3df381896b09fa76b52cd7a49b9b24afb3
Author: Tim Lange <mail@tim-lange.me>
Date:   Sun Jul 3 03:22:30 2022 +0200

    Use fixed-width types in allocation size tests
    
    The patch changes the types inside the tests for the allocation size
    checker to fixed-width types of stdint.h to account for different
    architectures with different type widths.
    
    2022-07-03  Tim Lange  <mail@tim-lange.me>
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/analyzer/allocation-size-1.c: Use fixed-length types.
            * gcc.dg/analyzer/allocation-size-2.c: Likewise.
            * gcc.dg/analyzer/allocation-size-3.c: Likewise.
            * gcc.dg/analyzer/allocation-size-4.c: Likewise.
            * gcc.dg/analyzer/allocation-size-5.c: Likewise.
