patches.

type safety.

the asmparser didn't.

getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

CV-qualifiers. Remove an error expectation from the 'good' set of const-cast
test cases. With this patch, the final non-template test case from PR5542
passes. (It's the same as the one already in const-cast.cpp.)

more or less cv-qualified than another during implicit conversion and overload
resolution ([basic.type.qualifier] p5). Factors the logic out of template
deduction and into the ASTContext so it can be shared.

This fixes several aspects of PR5542, but not all of them.

address resolution. This fixes PR5751.

Also, while we're here, remove logic from ADL which mistakenly included the
definition namespaces of overloaded and/or templated functions whose name or
address is used as an argument.

why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.
