Fix for PR4721: adjust CodeGen and ASTContext so that we have a
...
consistent model for handling size expressions for VLAs.
The model is essentially as follows: VLA types own their associated
expression. In some cases, we need to create multiple VLA types to
represent a given VLA (for canonical types, or qualifiers on array types,
or type merging). If we need to create multiple types based off of
the same VLA declaration, we use the new refcounting functionality so they can
all own the expression. The VLASizeMap in CodeGenFunction then uses the size
expression to identify the group of VLA types based off of the same original
declaration.
I'm not particularly attached to the VLA types owning the expression,
but we're stuck with at least until someone comes up with a way
to walk the VLA expressions for a declaration.
I did the parallel fix in ASTContext for DependentSizedArrayType, but I
haven't really looked closely at it, so there might still be issues
there.
I'll clean up the code duplication in ASTContext in a followup commit.

Change handling of attribute 'malloc' to only accept the attribute on function
...
declarations (and not function pointers). This is consistent with GCC. Accepting
this attribute on function pointers means that the attribute should be treated
as a type qualifier, which apparently is not what GCC does. We obviously can
change this later should we desire to enhance the 'malloc' attribute in this
way.
