OptTable treats arguments starting with / that aren't a known option
as filenames. This means lld-link's and clang-cl's typo correction for
unknown flags didn't do spell checking for misspelled options that start
with /.
I first tried changing OptTable, but that got pretty messy, see PR41787
comments 2 and 3.
Instead, let lld-link's and clang's (including clang-cl's) "file not
found" diagnostic check if a non-existent file looks like it could be a
mis-spelled option, and if so add a "did you mean" suggestion to the
"file not found" diagnostic.
While here, make formatting of a few diagnostics a bit more
self-consistent.
Fixes PR41787.

This makes the output of some flag names in warning messages consistent with
the output of /? and the output of flags in most other diagnostics.

Summary:
This adds support for reporting multiple errors in a single invocation of lld-link. The limit defaults to 20 and can be changed with the /ERRORLIMIT command line parameter, or set to unlimited by passing a value of 0.
This is a new attempt after r295507, which was reverted because opening files raced with exiting early, causing the test to be flaky. This version avoids the race by exiting before calling enqueuePath.

Behavior races on ErrorCount. If the enqueued paths are evaluated
eagerly (in enqueuePath) then the behavior is as the test expects. But
they may not be evaluated until the future is waited on, in run() -
which is after the early return/exit on ErrorCount. (this causes the
test to fail (because in the "/ERRORCOUNT:XYZ" test, no other errors
are printed), at least for me, on linux)
This reverts commit r295507.
