Update this diagnostic to mention the reason (unmatched '['), matching
the other diagnostic about stray '\'. The original pattern is omitted,
as some users may mention the original pattern in another position, not
repeating it.
As we don't sort local symbols, don't sort non-local symbols. This makes
non-local symbols appear in their register order, which matches GNU as. The
register order is nice in that you can write tests with interleaved CHECK
prefixes, e.g.
```
// CHECK: something about foo
.globl foo
foo:
// CHECK: something about bar
.globl bar
bar:
```
With the lexicographical order, the user needs to place lexicographical smallest
symbol first or keep CHECK prefixes in one place.
llvm-readobj currently has a bug (see PR40097) where it prints '@' at
the end of unversioned dynamic symbols. This bug will be fixed in a
separate later commit, but these tests need fixing first.

GNU ld supports [chars] wildcards in version scripts, to match a single instance of any of the chars.
Here is an extern example from libstdc++'s version script in FreeBSD:
extern "C++"
{
...
std::locale::_[T-Za-z]*;
std::[A-Zm]*;
std::n[^u]*;
std::nu[^m]*;
std::num[^e]*;
...
}
Patch adds support for scripts above. This is PR29093.
