    testsuite: don't test for shirnk wrapping for arm thumb1 on pr46555.c [PR123751]
    
    Thumb1 does not support shrink wrapping so the check for shrink
    wrapping in pr46555.c needs to be disabled for that. It does work
    with both thumb2 and arm modes.
    
    Pushed after testing for arm with `-mthumb -march=armv8-m.base`,
    `-marm -mcpu=cotext-a72` and `-mthumb -mcpu=cotext-a72` to make
    sure the correct tests are happening and still pass.

            * gcc.dg/tree-ssa/pr46555.c: Disable for arm thumb1.
