Previously, it didn't support the character class, so we couldn't
eliminate the use fo llvm::Regex. Now that it is supported, we
can remove compileGlobPattern, which converts a glob pattern to
a regex.
This patch contains optimization for exact/prefix/suffix matches.

Fixed code that was not checked before on windows for me, because of testcases that are
disabled on that platform atm.
Inital commit message:
"[ELF] - Versionscript: do not treat non-wildcarded names as wildcards."
Previously we incorrectly handled cases when symbol name in extern c++ tag
was enclosed in quotes. Next case was treated as wildcard:
GLIBCXX_3.4 {
extern "C++" {
"aaa*"
}
But it should have not. Quotes around aaa here means that we should have do exact
name matching.
That is PR30268 which has name with pointer is interpreted as wildcard by lld:
extern "C++" {
"operator delete[](void*)";
Patch fixes the issue.

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.

Symbols.cpp contains functions to handle ELF symbols.
demangle() function is essentially a function to work on a
string rather than on an ELF symbol. So Strings.cpp is a
better place to put that function.
This change also make demangle to demangle symbols unconditionally.
Previously, it demangled symbols only when Config->Demangle is true.
