llvm: support for opaque pointers
...
Will be the default starting with LLVM 15, and required with LLVM 16.
Tested with LLVM 14 and '-mllvm -opaque-pointers'. See
https://releases.llvm.org/14.0.0/docs/OpaquePointers.html for more
information.

nllvmadd: fix not always forcing pointer constants in registers

There could have been a typeconversion around the pointerconstn/niln.
This was hidden because llvmtype fixed it up later, but with opaque
pointers it showed up again.

dbgllvm: struct_metadef fixes

It will be used to hold a reference to the underlying structure of a class,
whose type is represented as a pointer to a DW_TAG_class_type for compatibility
with the debug information generated by the FPC backend (otherwise we could
instead just add a deref expression to all variables of such a type)

hlcgobj: new getlocal and recordnewsymloc methods

Call hlcg.getlocal instead of tg.getlocal when used for actual parameters/local
variables. Has an extra tsym parameter, which will enable the LLVM backend to
insert debug information.
Call hlcg.recordnewsymloc when the location of a (local/para) symbol changes,
so debug info tracking can be updated (only done for LLVM currently)

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.
