C++1y: support for 'switch' statements in constexpr functions. This is somewhat
...
inefficient; we perform a linear scan of switch labels to find the one matching
the condition, and then walk the body looking for that label. Both parts should
be straightforward to optimize.

Factor out duplication between lvalue-to-rvalue conversions and variable

assignments in constant expressions. No significant functionality changes
(slight improvement to potential constant expression checking).

C++1y constexpr extensions, round 1: Allow most forms of declaration and
...
statement in constexpr functions. Everything which doesn't require variable
mutation is also allowed as an extension in C++11. 'void' becomes a literal
type to support constexpr functions which return 'void'.
