Split profile recording from jit compilation
We still use ProfileInfo objects to record profile information. That
gives us the flexibility to add the inline caches in the future and the
convenience of the already implemented GC.
If UseJIT is false and SaveProfilingInfo true, we will only record the
ProfileInfo and never launch compilation tasks.
