adeb8c93e9 * Set pi_do_call flag explicitly when procedure has a parameter or local var that require finalization. Normally it is set by implicit try..finally node, but this node is absent when compiling in {$implicitexceptions off} mode. This may cause internal errors in pass 2 if pi_do_call has not been set by other means. 
Fixes IE when compiling Lazarus for MIPS target.
+ Test.

eb419b58c5 - disable inlining of routines that contain a call to a C-style varargs

af43e5e3e9 Fix for Mantis #24872. 
psub.pas, tcgprocinfo.parse_body:
  * also check record symtables besides object symtables to determine whether the staticsymtable is accessed from a globally declared generic
  * use a translateable message if the static symtable is accessed if it should not
msg/errore.msg:
  + add new error message for when the static symtable is accessed from a global generic
msgidx.inc & msgtixt.inc:
  * regenerated

+ added test

0b4d54fcb9 - Delete all position markers from assembler code before optimization. Markers of this kind are not used by optimizer and are expected to be ignored, but ignoring them requires numerous checks in all target-specific optimizers and currently isn't done correctly. In turn, failure to ignore markers prevents optimization of procedure prologues and epilogues.

96dd464bf2 * Moved fixup_jmps to target-specific classes for powerpc,powerpc64 and MIPS, cleaned out remaining $ifdef's. A slight functionality change is that fixup_jmps is now called before adding the procedure end symbol, not after, but that should not matter.

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

686a2d2f3f + Support omitting the frame pointer on arm even in procedures with incoming parameters 
on the stack, this can be enabled by -OoFORCENOSTACKFRAME. This reduces the required
  entry/exit code and makes an extra register available to the compiler. However, since this is
  based on an estimation of the required stack size, it might have two drawbacks:
  either the stack frame is estimated to big, the program requires a bigger stack than needed
  or it is estimated too small, then the compiler throws an internalerror during compilation. These
  issues can be overcome as soon as the compiler supports recompiling subroutines if needed.

f936a48afa * don't change the forward/interface definition of regular forward/interface 
functions whose implementation is declared "external". This results in less
    efficient code (all calls will go through a stub), but it prevents interface
    crc changes (-> no recompilations in case of circular dependencies) and it
    also keeps the interface stable (if the external implementation is changed
    afterwards to another external routine or to a local implementation, the
    mangled name of the routine does not change) (mantis #24121)

1ac4021178 * moved po_has_inlininginfo from procoptions to procimploptions so that 
the availability of the body of a function declared as "inline" no

52af9a2c89 * Changed passing of hidden parameters to constructors of class-style objects: VMT is always passed in the first ('self') parameter, and the second one ('vmt', although this name is now misleading) contains flag specifying the constructor behavior and meaning of 'self'. Together with r26656 this removes methodpointer sharing between two parameter node trees, it becomes possible not to put methodpointer into temp, but use node tree below 'self' parameter to do virtual calls. This also matches behavior of Delphi.
