[libcxx] Fix definition of regex_traits::__regex_word on big-endian glibc systems
...
Summary:
On glibc, the bits used for the various character classes is endian dependant
(see _ISbit() in ctypes.h) but __regex_word does not account for this and uses
a spare bit that isn't spare on big-endian. On big-endian, it overlaps with the
bit for graphic characters which causes '-', '@', etc. to be considered a word
character.
Fixed this by defining the value using _ISbit(15) on MIPS glibc systems. We've
restricted this to MIPS for now to avoid the risk of introducing failures in
other targets.
Fixes PR26476.

re.results.form: Format out-of-range subexpression references as null
...
Rather than crashing in match_results::format() when a reference to a
marked subexpression is out of range, format the subexpression as empty
(i.e., replace it with an empty string). Note that
match_results::operator[]() has a range-check and returns a null match
in this case, so this just re-uses that logic.

Cleanup: move visibility/linkage attributes to the first declaration.
...
This change moves visibility attributes from out-of-class method
definitions to in-class declaration. This is needed for a switch to
attribute((internal_linkage)) (see http://reviews.llvm.org/D13925 )
which can only appear on the first declaration.
This change does not touch istream/ostream/streambuf. They are
handled separately in http://reviews.llvm.org/D14409 .

Base regex code on char_class_type.
...
__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.
This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Implement LWG issue 2306: match_results::reference should be value_type&, not const value_type&. This is a general move by the LWG to have the reference type of read-only containers be a non-const reference; however, there are no methods that return a non-const reference to a match_result entry, so there's no worries about getting a non-const reference to a constant object.

Patch by GM: apparently '__value' (two underscores) is a special name in Visual Studio, so rename the private method in <regex> with that name.
