arm: add extra sizes to Wstrinop-overflow-47.c warning tests

[Andre Vieira]

A thumb2 target without a FPU like -mcpu=cortex-m3 will generate 'vector(4) 
char' stores which lead to warnings with sizes that weren't being allowed 
before by the test.  This patch adds these sizes.

gcc/testsuite/ChangeLog:

        * gcc.dg/Wstringop-overflow-47.c: Adjust warnings to allow for 32-bit
        stores.


OK for trunk and backport to gcc-15?

Kind regards,

Andre
