00a5d30300 LLVM: remove use of getelementptr in make_simple_ref_ptr 
We cannot safely infer whether it needs to be indirect or not there,
it should be done at a higher level if appropriate.

29bae2297f tcginnode.pass_generate_code: use tlhcgobj.g_undefined_ok 
Also override the code that uses this for LLVM with a variant that does not
need it for LLVM versions that do not support the freeze instruction.

ab581c5c30 LLVM: override thlcgobj.g_undefined_ok 
Uses the freeze instruction available in LLVM 10.0+. If we don't freeze undef/
poison values before using them in a calculation (even if that calculation is
something like "and 0", which masks the result completely), the result will
still be undef/poison and will keep propagating.

95f94a279c llvmdbg: fixes for method debug info

real type

657b9a6203 LLVM: support for -Sv (manual vector usage) 
Override register type for vectors to "integer registers" because we don't
use mmregister on LLVM (they're all virtual, so it doesn't matter)

25999ad8ff 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.

d45076d9d6 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.

value in LLVM (in case it changes across LLVM versions)

61f01ded61 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)

4c8249de34 dbgllvm: added appenddef_struct_named 
Factored out of appenddef_record_named for reuse by objectdefs.

Also moved responsibility of adding the struct dinode to the asmlist
to the caller, as the name of this method does not imply it will do
that.

25e832940c llvmdbg: support for generating debug information for local/para varsyms 
Note that not all symbols are covered yet, because absolutevarsyms are not
yet supported and those are e.g. used for function result aliases.
Additionally, not all types are fully supported yet.

a76038e1d1 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)

fe0048bcec 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"
