efc5e339d0 * use an enum instead of integer constants to represent inline numbers 
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
  their enum name, instead of number

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now

1e9491550d nutils.pas: Add new procedure: 
procedure node_change_local_switch(p : tnode;cs : tlocalswitch;enable : boolean);
    to add/remove cs local switch from all p tnode tree localsettings.

    modify second_prefetch implementation in arm, ppcgen and x86 subdirectories
    to use node_change_local_settings to temporarily disabled
    checkpointer local switch, as prefetch is allowed even on unaccessible addresses.
    (previous code was buggy because I frogot that each node has it own localswitches).

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol(): 
it was AT_NONE, which is invalid and should never be used
  * explicitly pass the correct value for all calls to those methods elsewhere

9079227c56 * don't give an internalerror when trying to prefetch a regvar or even 
something without a location at all; it's a hint/optional operation,
    so if there's nothing to prefetch just don't do anything
    (mantis #27811)

d88d644925 + support for FMA intrinsic: if there is no hardware support, the compiler throws an error. 
Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
  be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
  double operations, it makes no sense in my opinion to do so.

486a7ef81e * tx86inlinenode.second_popcnt: use emit_ref_reg instead of appending instruction directly, this provides proper PIC handling of the reference. emit_reg_reg part is not strictly necessary, but done for consistency.
