Add overflow values to the tests

[mr-c]

Examples from https://github.com/simd-everywhere/simde/pull/685

SIMDE_FLOAT32_C(-2147483650.0)
SIMDE_FLOAT32_C( 2147483649.0)

SIMDE_FLOAT64_C(-2147483650.0)
SIMDE_FLOAT64_C( 2147483649.0)

The procedure is:

1. Find tests that use SIMDE_FLOAT32_C or SIMDE_FLOAT64_C in their test_vec
2. Copy-n-paste an entry in the test_vec, modifying the inputs using the overflow values above. Don't worry about changing the expected result (r) yet.
3. Run the tests on a processor that supports the native intrinsic. Copy the correct output values from the error logs.
4. Send a PR
5. Repeat!
