An earlier change eliminated spaces between the close brackets of nested
template lists. Unfortunately that prevents the Windows debuggers from
matching some types to their corresponding visualizers (e.g., std::map).
This selects the SeparateTemplateClosers flag when generating CodeView.
Note that we were already making formatting adjustments under similar
circumstances for similar reasons.
This wasn't caught by existing tests because they were using only
-std=c++98.

vertical-line is not a BRE special character.
POSIX.1-2017 XBD Section 9.3.2 indicates that the interpretation of `\|`
is undefined. This patch uses an ERE instead.

When -gmlt is on, we don't emit namespace or class scope information,
and the CodeView emission code in LLVM can't compute the fully qualified
name. If we know LLVM won't be able to get the name right, go ahead and
emit the qualified name in the frontend.
We could change our -gmlt emission strategy to include those scopes when
emitting codeview, but that would increase memory usage and slow down
LTO and add more complexity to debug info emission.
The same problem exists when you debug a -gmlt binary with GDB, so we
should consider removing '&& EmitCodeView' from the condition here at
some point in the future after evaluating the impact on object file
size.
