[SYCL][E2E] Add lit expansion for floating point model (#15476)

ayylol · web-flow · commit a49684431403 · 2024-09-24T09:14:11.000-07:00
This option is set differently based on the compiler driver. With the
LLVM driver we need to use `-ffp-model=`, while with the MSVC driver we
would use `/fp:`

This patch introduces the expansion `%fp-model-` to address this.
