Code Gen: Use strict map rather than lazy map in loop analysis
We were ending up with a big 1GB thunk spike as the `fmap` operation did
not force the key values promptly.
This fixes the high maximum memory consumption when compiling the mmark
package. Compilation is still slow and allocates a lot more than
previous releases.
