Thomas Munro 4c8208c2b0 jit: Fix jit_profiling_support when unavailable. 
jit_profiling_support=true captures profile data for Linux perf.  On
other platforms, LLVMCreatePerfJITEventListener() returns NULL and the
attempt to register the listener would crash.

Fix by ignoring the setting in that case.  The documentation already
says that it only has an effect if perf support is present, and we
already did the same for older LLVM versions that lacked support.

No field reports, unsurprisingly for an obscure developer-oriented
setting.  Noticed in passing while working on commit 1a28b4b4.
