Import wrappers (wasm-to-js) were missing from profiling, since their
code is never logged.
This CL fixes this by generally logging all wasm code generated, not
just actual wasm functions.

Also, instead of logging each individual code object (which requires a
lock) within another lock, move the code out of the other lock and log
all code objects at once.
