  Log Message:
  -----------
  [SPIR-V] Reset SPIRVGlobalRegistry at module entry (#196058)

GlobalRegistry is owned by the TartgetMaching lifetime Subtarget but
caches IR pointers, so a reused TargetMachine (e.g. in case of JIT,
libFuzzer) would carry stale entries from a prior module

The bug was caught by `llvm-isel-fuzzer` ran for
`spirv64-unknown-unknown`
