llvm: changed llvm_metadatatype from untyped pointer to undefineddef
...
That matches its meaning better, as it should not result in type conversions.
E.g. some kinds of metadata parameters expect a "type register" parameter such
as "metadata i32* %reg.3"

llvmdbg: fix overflows for aggregates > 2^61 bytes
...
LLVM does not support aggregates larger than that at all, because internally
it stores all sizes in bits in an uint64. Their rationale for not having
special support for that is that there is no hardware with full 64 bit VM
address space anyway. So truncate our size emissions in debug info also to
that.

dbgllvm: remove restriction to only write struct procdef in context of struct

Does not make a difference for LLVM since all debug info for procdefs is
assigned to the definition instructions for the procdef anyway, and avoids
issues when only generating line info (in that case the structs will never
be processed, but we still have to generate the basic debug info for their
procdefs to provide a scope for their line info)
