David Blaikie aee4925507 Recommit: Compress formatting of array type names (int [4] -> int[4])
Based on post-commit review discussion on
2bd8493847 with Richard Smith.

Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).

This was originally committed in 277623f4d5

Reverted in f9ad1d1c77 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).

David Blaikie f9ad1d1c77 Revert "Compress formatting of array type names (int [4] -> int[4])"
Looks like lldb has some issues with this - somehow it causes lldb to
treat a "char[N]" type as an array of chars (prints them out
individually) but a "char [N]" is printed as a string. (even though the
DWARF doesn't have this string in it - it's something to do with the
string lldb generates for itself using clang)

This reverts commit 277623f4d5.

Aaron Ballman ad672ffb64 Support accepting __gnu__ as a scoped attribute namespace that aliases to gnu.
This is useful in libstdc++ to avoid clashes with identifiers in the user's namespace.

Alex Lorenz 757a69b760 [Sema] Handle transparent_union attributes in C mode only
This commit marks the transparent_union attributes as C only because clang
doesn't support them in C++ mode. Prior to this commit, clang still tried to
verify these attributes in C++, leading to crashes when analyzing templated
transparent_union unions that have dependent field types. This commit ensures
that such crashes won't happen again.

As a result of this commit clang now displays a warning every time it encounters
a transparent_union attribute in C++ mode.

Fariborz Jahanian b91c5d6a79 Patch to warn if 'override' is missing
for an overriding method if class has at least one
'override' specified on one of its methods.
Reviewed by Doug Gregor. rdar://18295240
(I have already checked in all llvm files with missing 'override'
 methods and Bob Wilson has fixed a TableGen of FastISel so
 no warnings are expected from build of llvm after this patch.
 I have already verified this).

Aaron Ballman 5d153e3133 Diagnose GNU-style attributes preceding virt-specifiers, but only when the attribute is known to GCC. Clang accepts attributes in this position, but
GCC does not, so this is a GCC-compat warning. If the attribute is not known to GCC, then the diagnostic is suppressed.
