This patch renames two of the SPIR-V tests to `*.spvasm` since both files are assembly files, rather than SPIR-V binaries. The `lit.cfg.py` is adjusted and we no longer need to run `*.spv` tests since none are present.

|
|
; COM: after it, is not sunk into that selection region by the deserializer. If the
