108d3cb090 - Removed tai_label.is_global field, was used in just one place and is generally not needed: binding is controlled by 'bind' property of referenced AsmLabel.

4ec9ec2009 + PIC support for Darwin/ARM: 
o does not use GOT
   o enabled by default like for other Darwin platforms
  - removed Darwin/ARM call stub support: no longer needed with current
    Xcode versions (at least Xcode 4.2+), and we didn't support PIC
    in them yet

17ef986b17 compiler: don't treat methods without self node (static class methods, class contructors, destructors, operators) as method pointers, fix comparison of procdef and procvardef to allow assignment of a static class method to a regular procedural variable (issue #24486)

38058505ba * Changed linking infrastructure to look like assembler one: 
* Changed direct references to linker classes in TSystemInfo records to enumerated ids.
  * RegisterExtennalLinker and RegisterInternalLinker procedures replaced by single RegisterLinker procedure and moved to link.pas.
  - TAbstractLinker is no longer necessary, removed.

This change allows to register linker once per id, rather than once per target, and also allows TSystemInfo records to be read-only.

eec8129738 * TInternalLinker.Load_ReadStaticLibrary: exit if error has occurred while opening a static library or dynamic object, continuing can cause other errors/crashes in this case.

d11ec8ac47 - Reverted r25269 and commented out r25261. The former one is wrong because it changes unit initialization order. The latter one causes RTL build failures on some targets, needs testing and likely RTL/makefiles patching.

e1ddd914ac * Do not implicitly load Variants unit when compiling units. Doing so is mostly waste of time, and introduces unwanted build dependencies. It is enough to set uf_uses_variants flag for units, and examine these flags when compiling program/library. Resolves #24880.

d8c84706dd * use Tai_symbol.Create_global() when emitting a global symbol for an 
abstract method wrapper (tai_symbol.create() currently overrides the
    symbol type from global to local; will fix in next commit)
  * only generate global abstract method wrappers for the class in which
    the abstract method is declared to prevent duplicate symbol errors
