a6c7ed5e61 vector support: use vector result types 
Set the result of a vector add node to a vector type.

Ensure that that these vector types are still asignment-compatible with
regular array types (may want to change this when we expose vector types),
and don't remove type conversions from vector types to array types (so the
code generator pass can still rely on the resultdef being a vector type)

2808873d1b * Reworked the optimization of unused $parentfp for nested routines. 
- 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;

1da43f67d4 * (non-ancient) Delphi versions that accept explicit ordinal -> floating

    as Turbo Pascal (reinterpret the bit pattern) (mantis #35886)

c038e4c3f2 * relaxation of r42272: again only show warnings rather than errors for 
out-of-range constants, because of the comments mentioned in #35753
    (except for enums, as apparently Delphi does the same)
  * added range check warnings about explicit type casts that throw away
    bits (e.g. byte($fff)), without giving warnings for most common cases
    (like cardinal(-1))
  * fixed masking/sign exting constant array indices (must be based on index
    range type size/signedness rather than on array size/"signedness")

9bd931e931 * make "formal const/var" parameters the least preferred conversion
