05a8783b1e * patch by Nico Erfurth: 
Improve ARM-Peephole Optimizers

1.) Introduce a ARM-specific RegUsedAfterInstruction which analyzes
instructions and reg allocation information to see if a register is
really needed afterwards to decide if some special optimizations can be
done.

2.) Introduce "RemoveSuperfluousMove"
This tries to fold mov into a previous Data-Instruction (ADD, ORR, etc)
or LDR-Instruction.

3.) Introduce new Optimizer "DataMov2Data" and modify LdrMov2Ldr to use
RemoveSuperfluousMove

4.) Expand Ldr* and Str* Optimizers to also work on {Ldr,Str}{,b,h}

Inline a couple of small functions of the ARM-Compiler

These small changes improved overall compile times of the fpc suite by
about 2-3% running on an 1.2GHz Kirkwood.

edd42aa42a * moved subsetref/reg and bit_set/test support from cgobj to hlcgobj for 
future use by high level code generator targets
   o this in turn required that all a_load*_loc* methods are called via
     hlcg rather than via cg, since a location can be a subsetref/reg and
     and those are no longer handled in tcg
   o that then required moving several force_location_* routines into
     thlcg because they use a_load_loc*, but did not take tdef size
     parameters (which are required by the thlcg a_load_loc* routines)
   o the only practical consequence is that from now on, you have to
     use hlcg.location_force_mem/reg() (fpureg not yet) and
     hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
     and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
     might be involved

f95925dd91 * don't push/pop current_module.localsymtable when adding explicitly created 
pointer/arraydefs, because these operations can have side-effects in case
    of helpers (will add/remove helpers, so popping after the insertion
    removed all helpers in the static symtable of the current unit)

642a180809 Fix from Lacak2 for Mantis #21994 fixes 
* when records are inserted into empty dataset and then all canceled by CancelUpdates AV is raised
* another fix for bug #18004, applied in rev.20531 (improved in rev.21197)
  (original approach is not good because when record is inserted and deleted and again inserted,
   then same memory block can be returned, which leads to confusion, because we get same BookmarkData for distinct records)

b3595893c8 pgenutil.pas, generate_specialization: set the correct module index, so that warnings, etc. that are generated for a type declaration are printed using the module where the generic came from (this is already done for method bodies, but not for declarations)

810bd7ddab + symtable.pas, tspecializesymtable.create: SymList and DefList do not need to own the symbols and defs as they are moved to another symtable before the specialize symtable is destroyed (avoids the need to call "extract" on those lists) 
* pgenutil.pas, generate_specialization: Correctly change the ownership of extracted symbols and defs by calling ChangeOwner on the symbol/def which does all the magic of changing the owner and adding it to the corresponding list of the given symtable. This fixes Mantis #21550
* Adjusted tw21550.pp so that it enforces the generation of debug information which (as this was the option which caused the above mentioned bug to show)
