We used to only store the uses_super_property in the preparse data
logger. Let the logger use NeedsHomeObject instead.

This avoids accidental coercion-to-bool when calling ReportMessage()
in the parser (e.g., from pointer types), and as a bonus makes callsites
easier to read.

The preparser needs to log the usage of super properties and then update
the scope when we create the function later.

Removing it seems to be a clear win on mobile: producing symbol data makes cold
parsing 20-30% slower, and having symbol data doesn't make warm parsing any
faster.
Notes:
- V8 used to produce symbol data, but because of a bug, it was never used until
recently. (See fix https://codereview.chromium.org/172753002 which takes the
symbol data into use again.)
- On desktop, warm parsing is faster if we have symbol data, and producing it
during cold parsing doesn't make parsing substantially slower. However, this
doesn't seem to be the case on mobile.
- The preparse data (cached data) will now contain only the positions of the
lazy functions.
