testcase: Add testcase for PR 117330 [PR117330]

This testcase was causing an ICE during vectorization
due to r15-4695-gd17e672ce82e69 but was fixed with
r15-4713-g0942bb85fc5573.

Pushed as obvious after a quick test on x86_64-linux-gnu to
make sure the testcase passes.

	PR tree-optimization/117330

gcc/testsuite/ChangeLog:
