Simple testcase fix, ok for trunk?
This patch removes specific register checks to account for possible
register spills and disables tests in 32-bit mode. This adjustment
is necessary because V4BF operations in 32-bit mode require duplicating
instructions, which lead to unintended test failures. It fixed the
case when testing with --target_board='unix{-m32\ -march=cascadelake}'
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx10_2-partial-bf-vector-fma-1.c: Remove specific
register checks to account for potential register spills. Exclude tests
in 32-bit mode to prevent incorrect failure reports due to the need for
multiple instruction executions in handling V4BF operations.
