Richard Smith f8379a0fc3 constexpr: converted constant expression handling for enumerator values, case 
values and non-type template arguments of integral and enumeration types.

This change causes some legal C++98 code to no longer compile in C++11 mode, by
enforcing the C++11 rule that narrowing integral conversions are not permitted
in the final implicit conversion sequence for the above cases.

Richard Smith 0f8ee22655 Update C++11 scoped enumeration support to match the final proposal: 
- reject definitions of enums within friend declarations
 - require 'enum', not 'enum class', for non-declaring references to scoped
   enumerations

Eli Friedman 7c6515a653 Make sure we perform lvalue-to-rvalue conversions for enum initializers. PR11484.

Richard Smith 9ca5c42582 Update all tests other than Driver/std.cpp to use -std=c++11 rather than 
-std=c++0x. Patch by Ahmed Charles!

John McCall 21878760a4 Fixed enum types can be complete without actually being valid to use 
as scope specifiers;  diagnose the attempt, rather than letting it go
to an assert.  The rest of PR10264.

John McCall cb432faf6d Properly protect colons when parsing a nested-name-specifier as part 
of an enum specifier in dialects which permit fixed underlying types.
Fixes the rejects-valid part of PR10264.

Douglas Gregor 21673c4e7e Scoped enumerations should not be treated as integer types (in the C 
sense). Fixes <rdar://problem/9366066> by eliminating an inconsistency
between C++ overloading (which handled scoped enumerations correctly)
and C binary operator type-checking (which didn't).

Douglas Gregor 48e6bbffa1 Implement comparison of C++0x scoped enumeration types. Fixes PR9333.

Douglas Gregor 6cd5ae4dfa Fix a little bug in the handling of enumeration types with a fixed 
underlying type: we weren't parsing unnamed enumeration types with a
fixed underlying type.

Douglas Gregor 0bf3140424 Implement C++0x scoped enumerations, from Daniel Wallin! (and tweaked a 
bit by me).
