Nico Weber 71e377d6ee If a function decl cannot be merged, mark it as invalid. 
Clang currently crashes on

    class C {
      C() = default;
      C() = delete;
    };

My cunning plan for fixing this was to change the `if (!FnD)` in
Parser::ParseCXXInlineMethodDef() to `if (!FnD || FnD->isInvalidDecl)` – but
alas, the second constructor decl wasn't marked as invalid.  This lets
Sema::MergeFunctionDecl() return true on function redeclarations, which leads
to them being marked invalid.

This also improves error messages when functions are redeclared.

Serge Pavlov 2e3ecb660a Recover from errors in enum definition 
Previously any error in enum definition body stopped parsing it. With this
change parser tries to recover from errors.
The patch fixes PR10982.

Richard Smith 034185c2f9 The 'constexpr implies const' rule for non-static member functions is gone in 
C++1y, so stop adding the 'const' there. Provide a compatibility warning for
code relying on this in C++11, with a fix-it hint. Update our lazily-written
tests to add the const, except for those ones which were testing our
implementation of this rule.

Richard Smith 434516c50c Don't skip '_Alignas' when disambiguating 'final'. '_Alignas' can't appear here, 
and we used to assert if it did.

Richard Smith b19337fbe4 PR15311: Finish implementation of the suggested resolution of core issue 1488, 
which allows grouping parens in an abstract-pack-declarator. This was already
mostly implemented, but missed some cases. Add an ExtWarn for use of this
extension until CWG ratifies it.

Richard Smith 369b9f997c Extend the "expected ';' after struct" logic to also apply to enums, and to 
struct and enum forward-declarations.

Richard Smith 43f340f440 If we see '(...' where we're expecting an abstract-declarator, that doesn't 
necessarily mean we've found a function declarator. If the next token is not
a ')', this is actually a parenthesized pack expansion.

Richard Smith bfdb108fc5 Fix parsing of trailing-return-type. Types are syntactically prohibited from 
being defined here: [] () -> struct S {} does not define struct S.

In passing, implement DR1318 (syntactic disambiguation of 'final').

Richard Smith 1e3b0f0614 Update parser's disambiguation to cope with braced function-style casts in 
C++11, and with braced-init-list initializers in conditions. This exposed an
ambiguity with enum underlying types versus bitfields, which we resolve by
treating 'enum E : T {' as always defining an enumeration (even if it would
only successfully parse as a bitfield). This appears to be g++ compatible.
