* 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.

* 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.

* 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.

- 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.

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

* 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.
