07e90aaa24 + Implemented IEEE 754-compliant checking for unordered results of floating-point compares on x86 targets. Mantis #9362.

3555b76495 - rm FDISI,FENI,FSAVE,FSTCW,FSTENV and FSTSW from the requires_fwait_on_8087() 
list, because these instructions already have a built in FWAIT prefix even
  when targeting the 287/387+ both with the internal asm writer and with the
  NASM back end.

12b2f86e99 + added function requires_fwait_on_8087(), which checks whether a given 
instruction needs adding a FWAIT prefix on the i8087.

68dd05e259 * fixed std_regname() for xmm registers with custom sizes

e327b4581c Use TRegNameTable instead of array[tregisterindex] of string[10] 
TRegNameTable is defined in compiler/rgbase.pas and is an array of
strings, limited to the maximum length of the used register names.

r22792 added a long register name but did not scale the string-size
enough, resulting in the compiler built breaking for arm.

e11c880b1e x86 assembler improvements: 
* Don't generate rex.w for "CALL|JMP|LCALL|LJMP regmem", they are 64-bit by default.
* LCALL,LJMP flagged as calljump instructions.
* LCALL,LJMP encode only far jumps and don't accept register operands.
* GAS writer: fixed writing rip-relative operands of calljump instructions.
+ test.

58d1a66cd0 * set max_operands to 4 on x86 to be prepared for avx and to be able to fix #19910, 
- memory usage of a compiler compilation increases by approx. 2 per cent due to this
  - actually docs say avx has operations with 5 parameter, however I were not able to find
    an instruction having 5 operands

34c985cfa6 * added register type parameter to cgsize2subreg(), as the subreg can 
depend on that (and correct a number of cases where this was wrong)
  * set the correct subreg type for xmm x86_64 parameter registers
    (resolved mantis #14067)

ec959955bd * fixed generic jumps optimizer and enabled it for ppc (the label table 
was not being initialised -> getfinaldestination always failed, which
    caused wrong optimizations in some cases)
  * changed the inverse_cond into a function, because tasmcond is a record
    on ppc
  + added a compare_conditions() function for the same reason
