This change fixes a crash on initialization of a reference from ({}) during
template instantiation and incidentally improves diagnostics.
This reverts a prior attempt to handle this in r286721. Instead, we teach the
initialization code that initialization cannot be performed if a source type
is required and the initializer is an initializer list (which is not an
expression and does not have a type), and likewise for function-style cast
expressions.

T in the expression T() must be a non-array complete object type or
the void type. Function types are neither.
This fixes PR24798.

function-style cast. Previously, we had a (redundant, incorrect)
semantic-checking path for non-class types, which allowed
value-initialization of a reference type and then crashed.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

-The Parser calls a new "ActOnCXXTypeConstructExpr" action.
-Sema, depending on the type and expressions number:
-If the type is a class, it will treat it as a class constructor. [TODO]
-If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node
-If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node.
