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.

256c852631 Fix for Mantis #23776. 
ninl.pas, tinlinenode.pass_typecheck:
  * don't generate a type error if Length() is used inside generics with a generic argument

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

a08e8ff982 Fix for Mantis #25929 
* ninl.pas, tinlinenode.handle_default.getdefaultvarsym:
    prefix the default variable's name with a "$zero" instead of a "zero" and use only the string from the second character on for comparisons so that findwithhash() and checkduplicates() generate consistent results

e1332304ef * when converting Hi() to a shr node, convert the right shr const parameter to 
sinttype, instead of u32inttype. This:
  1) is consistent with what type conversion tshlshrnode.pass_typecheck inserts
     on the right side
  2) avoids the expensive conversion to 32-bit and the even more expensive
     performing the operation in 32-bit on i8086

d2b8275b99 + support for arbitrary encodings in readstr/writestr 
o set the code page of the temporary "text" file to utf-8 for writestr with
     unicodestring/widestring as destination, so that no data loss can occur
     (+ properly deal with cases whereby part of an utf-8 character is
      written to the textbuf in this case)
   o explicitly pass the code page of the destination ansistring for writestr
     with ansistring as destination and set it for the temporary "text" file
   o set the code page of the text file for readstr

8ecad469a6 * Reverted r26256 since it produced wrong results if argument of inc/dec is actually unaligned. Added description of the issue and slightly increased node complexity at which address is cached, so operations on record/class fields do not take address.

9ad98a2c4d * Handle "SarInt64" always as internal procedure, introduced virtual method tinlinenode.first_sar that by default converts it into call to "fpc_sarint64" unless target CPU is 64-bit. This provides a point to insert target-specific optimizations.

dac8cbcefc * Handle assigned(x) expressions entirely in first pass by converting them to "x<>nil", indicate that procedure variables should not be called by setting nf_load_procvar flag (which is already used with typeconvnode for exactly the same purpose).

b81f746e05 Inline Length(DynamicArray) 
Up until now a helperfunction was called at runtime. This change inlines
the whole code in the same way Length(AnsiString) works. As dynamic
arrays do not record their length but their highest index, an additional
"OP_ADD" is this case.
