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)

17256e8387 * fpc_exp_real: replaced pushing immediate values on stack with Darwin-style PIC. This change increases performance on Intel E7200 almost twice. On AMD CPUs performance increase is not that large, but still noticeable.

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.

b16c6f8ced * i386 and x86_64 changes for Delphi compatibility: 
* 'mxcsr' variable made public and renamed to DefaultMXCSR.
  * GetSSECSR and SetSSECSR renamed to GetMXCSR and SetMXCSR, respectively. Previous names continue to exist as deprecated aliases.

6810d643c4 * Fixed exp() result for +-Inf input, must be +Inf or 0, not NaN. This is mathematically correct and consistent with generic implementation of this function.

217bac7a0b - Removed fpc_pi_real compilerproc, it is no longer used. At least two releases (2.6.2 and 2.6.4) emit Pi directly as a constant.

2981f73aaa - Removed redundant functions "power", they were neither used nor accessible through interface. The actual function "power" is located in Math unit.

d251c131a5 * i386: replaced fpc_exp_real with a port from AMath library. It has better accuracy and is faster on CPUs that suffer penalties from changing x87 control word.

c35e0bf712 - removed fclex at the end of fpc_exp_real because it makes that routine 10+ 
times slower on P4/Athlon XP cpus, and removing it does not cause any test
    suite regressions

f51bac256d * made pic-safe (by simply not accessing global variables from 
assembler code anymore, as I don't see how to easily support
    PIC access to global variables for Darwin/i386)
