199b5809a3 * optimize "dynarr := dynarr + [elem]" to "Insert(elem, dynarr, High(SizeInt))" and "dynarr := [elem] + dynarr" to "Insert(elem, dynarr, 0)" (we need to do this in the typecheck of taddnode as otherwise the array constructor is already converted) 
+ added test
* adjusted test for Mantis #30463 as p1 triggers the optimization as well

6bd99b65bf + emit DW_AT_frame_base dwarf attributes on i8086. Even though the Watcom 
Debugger doesn't require them (it uses BP as the frame register by default),
  the dwarf spec requires that we emit them on i8086, because we also use
  DW_OP_fbreg on i8086.

c5fe78201c + emit DW_OP_bregx dwarf ops for local variables and parameters, relative to BP 
on i8086. This fixes Watcom Debugger not showing them right in memory models,
  where DS<>SS (Watcom seems to ignore the DW_AT_segment attribute for register
  relative variables, even though we emit it correctly :/ )

register that has a dwarf register number higher than 31

e5de7d0eac * set all 16/32-bit specific stabs/dwarf register numbers of x86_64-only 
registers to -1 in x86reg.dat. The values that used to be there weren't used
  at all (most were just copies of the 32-bit version of the register). This can
  be easily demonstrated by the fact that running 'make regdat' in the compiler
  directory doesn't change any of the generated files for i8086/i386/x86_64.

a275d15da2 + added an i8086-specific column in x86reg.dat for the dwarf register numbers 
and filled it with the dwarf register mapping, used by Open Watcom (Watcom
  also uses this mapping on i386, but we don't need to support their debugger on
  i386 for now)

nickysn
065a7b63d9 * changed the TObjSectionOfs type to be longword on i8086 
+ introduced the TObjSection.SizeLimit property. This will allow setting
  different size limits for different sections (e.g. 32-bit for the dwarf
  sections, 16-bit for the regular code and data sections on i8086).

nickysn
04129b8c6e + introduce the TObjSectionOfs type - an unsigned integer, representing an 
offset in an obj file section on the current platform; equal to PUInt for now,
  but will probably change to LongWord on i8086, in order to support 32-bit
  sections (needed for dwarf debug info or when linking with 32-bit object files
  in a mixed 16-bit/32-bit application, while using the internal linker)
