Don't disable JIT GC when instrumentation is enabled

Earlier we used to disable GC when there are instrumentation stubs or
the stack is instrumented due to some races in updating the entry
points. This is fixed now and we no longer need to disable JIT GC. The
disabling of the JIT GC wasn't accurate too, we were missing some places
where we don't disable GC (for ex: when instrumenting after the process
has started) which was also causing some DCHECK failures. This CL
updates it to not disable JIT GC even when we have instrumented code
and removes obsolete DCHECKs.

(partial cherry pick from
commit 162d74a1608a46007832470b8245265c576185d5 to remove obsolete DCHECKs)
