IncompleteArrayType.  This should make code dealing with both incomplete 
and variable length arrays much more readable, plus it allows properly 
making the distinction between isVariableArrayType() and 
isVariablyModifiedType().  The patch is a little big, but it's 
strightforward. so I don't think there should be any issues.

it follows the order of the enum, not alphabetical.
The motivation is to make -mattr=+ssse3,+sse41
select SSE41 as it ought to.  Added "ignored"
enum values of 0 to PPC and SPU to avoid compiler
warnings.
