Check whether we're in an extern inline function and referring to a variable or function with internal linkage (C11 6.7.4p3).
This is only a warning because we used to silently accept this code, but in many cases it will not behave correctly. This is not enabled in C++ mode because the restriction language is a bit weaker (C++11 [basic.def.odr]p6) and so while there may still be user mistakes, most of the time we can't prove that there are errors.

Simple conversion between integer and floating point types.
Used when handling the OpenCL conditional operator where the condition is a vector while the other operands are scalar.
OpenCL v1.1 s6.3.i and s6.11.6 together require that the scalar types are either integer or floating type. Between the two operands, the type with the higher rank is defined as the "result type". The other operand needs to be promoted to the same type. No other type promotion is allowed. We cannot use UsualArithmeticConversions() for this purpose, since it always promotes promotable types.

Convert scalar operands to a vector that matches the condition in length.
Used when handling the OpenCL conditional operator where the condition is a vector while the other operands are scalar.
We first compute the "result type" for the scalar operands according to OpenCL v1.1 s6.3.i. Both operands are then converted into a vector of that type where the length matches the condition vector type. s6.11.6 requires that the element types of the result and the condition must have the same number of bits.

In Microsoft mode, if we are inside a template class whose parent class has dependent base classes, and we can't resolve an unqualified identifier, then assume the identifier is a member of a dependent base class.
We can only recover successfully in static methods, instance methods, and other contexts where 'this' is available. This doesn't precisely match MSVC's instantiation model, but it's close enough.
