- Vect: Unrestrict test cases for non-gather elementwise loads.
- tldr
- Test cases for vectorization of non-gather elementwise loads are no longer specific to early break vectorization and are unrestricted.
- why_it_matters
- Ensures test cases are not unnecessarily restricted to specific vectorization techniques, allowing for broader testing of vectorization capabilities.

The test cases ‘g++.dg/vect/vect-pr124037.cc’ and ‘gcc.dg/vect/vect-pr124037.c’ were previously restricted to early break vectorization. This commit removes those restrictions, allowing the test cases to be used more broadly. The C++ test case also no longer uses ‘mmap’.
