Detailed Description

ExtQuals - We can encode up to four bits in the low bits of a type pointer, but there are many more type qualifiers that we want to be able to apply to an arbitrary type. Therefore we have this struct, intended to be heap-allocated and used by QualType to store qualifiers.

The current design tags the 'const', 'restrict', and 'volatile' qualifiers in three low bits on the QualType pointer; a fourth bit records whether the pointer is an ExtQuals node. The extended qualifiers (address spaces, Objective-C GC attributes) are much more rare.
