Do not eagerly set stop point for arguments. This misleads the debugger in identifying beginning of function body. Instead, create new location to attach with llvm.dbg.declare. This location is only used to find the context of the variable by the code generator, and it is not used to emit line number info.

Do not emit linkage name for global variables. It confuses gdb, because it picks up AT_MIPS_linkage_name and ignores AT_name.

Don't assert when trying to generate debug info for vector types. This needs to be fixed eventually...

Do not eagerly cache DITypes because it allows real struct type to be shadowed by forward declared struct type.

directly in the type system.

Please complain if you were using these classes and feel you can't replicate
previous functionality using the TypeLoc API.

Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.

Ok, an AssertingVH definitely doesn't work for now because we free our cache after the optimizer may have hacked on the module. Use a WeakVH instead.

directly in the AST.  The current thinking is to create these
only in C++ mode for efficiency.  But for now, they're not being
created at all; patch to follow.

This will let us do things like verify that tags match during
template instantation, as well as signal that an elaborated type
specifier was used for clients that actually care.

Optimally, the TypeLoc hierarchy should be adjusted to carry tag
location information as well.

This is a Type subclass that can hold a DeclaratorInfo* when we have type source info coming
out of a declarator that we want to preserve. This is used only at the "border" of Parser/Sema for
passing/getting QualTypes, it does not participate in the type system semantics in any way.
