975195e466 Remove redundant arguments in reduce_and_compute 
The A and DA arguments in reduce_and_compute are useless and hence
have been removed.

5ff8d60ef3 Remove some redundant computations in s_sin.c 
There are multiple points in the code where the absolute value of a
number is computed multiple times or is computed even though the value
can only be positive.  This change removes those redundant
computations.  Tested on x86_64 to verify that there were no
regressions in the testsuite.

8d561986c0 Minor code cleanup in s_sin.c 
- Remove redundant mynumber union definitions
 - Clean up a clumsy ternary operator
 - Rename TAYLOR_SINCOS to TAYLOR_SIN since we're only expanding the
   sin Taylor series in it.

10e1cf6b73 Add systemtap markers to math function slow paths 
Add systemtap probes to various slow paths in libm so that application
developers may use systemtap to find out if their applications are
hitting these slow paths.  We have added probes for pow, exp, log,
tan, atan and atan2.

5739f705ee Use integral constants 
The compiler is smart enough to convert those into double for powerpc,
but if we put them as doubles, it adds overhead by performing those
operations in floating point mode.

6f2e90e78f Make mantissa type of mp_no configurable 
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.
