it, instead of using {$calling stdcall} in the go32v2 ports unit

26a3ac3fd4 * moved the fpc_in_x86_*port* constants to the system unit in cpuinnr.inc in the 
i8086, i386 and x86_64 rtl directories. This is done for consistency with
  other compiler internal function numbers (which are declared in innr.inc).

d1e091d5a3 Use .byte substitutes for ldmxcsr and stmxcsr instructions 
if OLD_ASSEMBLER macro is defined.

  Do not use PIC code for fpc_exp_real if OLD_ASSEMBLER is defined
  (this generates unsupported relocations for GNU assembler 2.6 used by EMX)

88b58c3580 i386: added signed 64bit div/mod helpers in assembly. we have some 64bit heavy code where a direct helper results in about 8-10% of performance advantage compared to going through the generic wrapper + the unsigned function

fc5f45f65c * sqr(real) and sqrt(real): remove typeconv node inserted by initial call processing (see explanation in comments), allowing these functions to be evaluated using precision of argument. In particular, sqrt(single) and sqrt(double) now emit 'sqrtss' and 'sqrtsd' instructions on x86 targets with -Cfsse3. Non-x86 targets already have the necessary support in code generators. 
* abs(real): handle the same way as sqrt and sqr, i.e. without casting to bestreal and back.
