Richard Smith 22c7c4131a Teach statement / declaration disambiguation about C++11-style generalized initializers.

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 45fbfc7f11 Do not warn about a function decl / direct init ambiguity if the function has a trailing return type.

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.

David Blaikie 9933a5abab Fix a crash-on-invalid found by -Wlogical-op-parentheses.

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.
