[jit] Fix error-handling within gcc::jit::context::compile (timevar issues)

[David Malcolm]

Committed to dmalcolm/jit:

gcc/jit/
        * internal-api.c (gcc::jit::context::compile): Correctly cleanup
        timevars in error-handling, preventing an issue where an error
        on a context left timevar.c in an unstopped state, leading to an
        assertion failure when restarting timevars in the next compile.
        Found via fuzz-testing.
