[flang-commits] [flang] [flang][test] Run Driver/fveclib-codegen.f90 for x86_64 (PR #103730)

`Flang :: Driver/fveclib-codegen.f90` currently `FAIL`s on SPARC, both Solaris/sparcv9 and Linux/sparc64:
```
bin/flang-new -S -Ofast -fveclib=LIBMVEC -o - /vol/llvm/src/llvm-project/local/flang/test/Driver/fveclib-codegen.f90

flang/test/Driver/fveclib-codegen.f90:11:10: error: CHECK: expected string not found in input
! CHECK: _ZGVbN4vv_powf
         ^
```
The code in question only contains calls to `powf`.  Given that `glibc` only supports `libmvec` on `aarch64` and `x86_64`, this test needs to target either of those to work.

Tested on `sparcv9-sun-solaris2.11`, `sparc64-unknown-linux-gnu`, `amd64-pc-solaris2.11`, and `x86_64-pc-linux-gnu`.
