Summary:
The f64 compatibility added by D25079001 (e91552fefe) changes the `{rev}` template output.
However, the revset object is not aware of the rev mapping so the following
pattern will stop working:
ifcontains(rev, revset('.'), '@', 'o')
# rev: mapped, but not contains in `revset('.')`
Fix it by teaching `ifcontains(a, b, ...)` to disable f64 compatibility when
evaluating `a`, since `a` is not going to be printed out.
This fixes an issue in VSCode ISL that "You are here" is missing on non-master
commits.

Summary:
With segmented changelog, rev can exceed f64 safe range
(Number.MAX_SAFE_INTEGER in Javascript, 9007199254740991, 0x1fffffffffffff).
If rev is used in JSON, then the JSON cannot be parsed with precise rev
information.
This diff adds a compatibility mode so template will map the out-of-range revs
to safe range, and the mapped revs can be detected, and mapped back to be
resolved correctly.
