Akira Hatanaka 10aced824a [Parser] Clear the TemplateParamScope bit of the current scope's flag
if we are parsing a template specialization.

This commit makes changes to clear the TemplateParamScope bit and set
the TemplateParamParent field of the current scope to null if a template
specialization is being parsed.

Before this commit, Sema::ActOnStartOfLambdaDefinition would check
whether the parent template scope had any decls to determine whether
or not a template specialization was being parsed. This wasn't correct
since it couldn't distinguish between a real template specialization and
a template defintion with an unnamed template parameter (only template
parameters with names are added to the scope's decl list). To fix the
bug, this commit changes the code to check the pointer to the parent
template scope rather than the decl list.

Richard Smith a91de375f2 Promote a warning on ill-formed code (redeclaration missing an exception
specification) to an error. No compiler other than Clang seems to allow this,
and it doesn't seem like a useful thing to accept as an extension in general.

The current behavior was added for PR5957, where the problem was specifically
related to mismatches of the exception specification on the implicitly-declared
global operator new and delete. To retain that workaround, we downgrade the
error to an ExtWarn when the declaration is of a replaceable global allocation
function.

Now that this is an error, stop trying (and failing) to recover from a missing
computed noexcept specification. That recovery didn't work, and led to crashes
in code like the added testcase.

Richard Smith 410cc89374 [c++1z] Most of N4268 (allow constant evaluation for non-type template arguments).
We don't yet support pointer-to-member template arguments that have undergone
pointer-to-member conversions, mostly because we don't have a mangling for them yet.

Richard Smith 18819307d3 DR101, PR12770: If a function is declared in the same context as a

the using-declaration is in the same namespace as the declaration it
imports, or because they're both extern "C"), they do not conflict.

Richard Smith a230224be4 Implement DR482: namespace members can be redeclared with a qualified name
within their namespace, and such a redeclaration isn't required to be a
definition any more.

Update DR status page to say Clang 3.4 instead of SVN and add new Clang 3.5
category (but keep Clang 3.4 yellow for now).

Richard Smith 8b86f2d401 Implement final resolution of DR1402: implicitly-declared move operators that
would be deleted are still declared, but are ignored by overload resolution.

Also, don't delete such members if a subobject has no corresponding move
operation and a non-trivial copy. This causes us to implicitly declare move
operations in more cases, but risks move-assigning virtual bases multiple
times in some circumstances (a warning for that is to follow).

Richard Smith fb8b7b9a1c PR17567: Improve diagnostic for a mistyped constructor name. If we see something
that looks like a function declaration, except that it's missing a return type,
try typo-correcting it to the relevant constructor name.

In passing, fix a bug where the missing-type-specifier recovery codepath would
drop a preceding scope specifier on the floor, leading to follow-on diagnostics
and incorrect recovery for the auto-in-c++98 hack.
