Be consistent about deciding whether to print pass data.

`print_time_passes_entry` unconditionally prints data about a pass. The
most commonly used call site, in `VerboseTimingGuard::drop`, guards it
with a `should_print_passes` test. But there are a couple of other call
sites that don't do that test.

This commit moves the `should_print_passes` test within
`print_time_passes_entry` so that all passes are treated equally.
