This happens both with sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11
compilers.
A reghunt identified the following patch as the culprit:

summary: Use extract_bit_field_as_subreg for vectors
* expmed.c (extract_bit_field_1): For vector extracts,
fall back to extract_bit_field_as_subreg if vec_extract
isn't available.
For the tests that time out during compilation (haven't tried to determine if
they complete in more than 5 minutes), the patch for PR middle-end/83675
is required as well.
