Extend dead code detection to not only look for the main mangled name, but also
for any aliases before deciding that a routine has been dead-stripped.
Assume objects/classes can also be constructed if the address of one of their
constructors or of the TObject.NewInstance class method has been taken.
Resolves#40204
* Added the tprocdef.parentfpsym property. Set parentfpsym.varstate to vs_read instead of using the pio_needs_parentfp flag.
* Replaced tcgcallparanode.push_zero_sized_value_para by tparamanager.has_strict_proc_signature.

- Do not remove the $parentfp parameter as was done in the previous optimization approach. Instead when $parentfp is unused to the following:
- On the caller side: Omit passing the value for $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=false (classic CPU targets).
Pass 0/nil as $parentfp for targets where tcgcallparanode.push_zero_sized_value_para=true;
- On the callee side: Prevent allocation of registers/resources for $parentfp.
- When possible keep $parentfp in a register.
- Set the pio_nested_access flag in tprocinfo.set_needs_parentfp() to properly handle deep nesting levels;

that expects an open array of byte, and use it for all sets
o since all sets need to be typecasted to an array type of the appropriate
size, we'll get a compilation error in case this needs to be done and
that also tells us at the same time that the ppu version will need to
be increased
* enabled {$packset 1} for the compiler, as this is now safe with the above
changes

Allows compilation of compiler using -dDEBUG_NODE_XML
which will generate a NAME-node-dump.xml file for each
unit, program or library compiled,
containing a XML description of the nodes handled during
compilation of the unit, program or library.

o The @ and Addr() operators in TP or Delphi mode can now be applied to both
near and far procedures and they always produce a CodePointer, regardless of
the call model of the procedure.
o Ofs() and Seg() can now also be applied to both near and far procedures.
o The @ and Addr() operators in non-TP/Delphi modes, as well as the procedure
name itself in TP/Delphi modes now can be applied to both near and far
procedures and produce a near or a far procvar.

generator to the typecheck pass, so that it also works for platforms
that use the parentfpstruct way to handle accesses to nested frames
in case the array has been migrated to such a parentfpstruct
o additionally, the number of comparisons for such range checks
has been reduced from 3 (for signed indices) or 2 (for unsigned
indices) to 1 in all cases
o the range checking code is disabled for the JVM target, as the
JVM automatically range checks all array accesses itself anyway

all of their values, when kept in a bitpacked array, properly via
pass_typecheck rather than hacking location.size in pass_generate_code:
o the old fix was incomplete (it didn't handle non-constant indices)
o the old fix didn't work for llvm (since it uses defs rather than
location.size)
