0e9be4db8f Remove various ABS macros and replace uses with fabs (or in one case abs)
which is more efficient on all targets.

1cadc85813 Fix sign of input to bsloww1 (BZ #16623)
In 84ba214c, I removed some redundant sign computations and in the
process, I incorrectly got rid of a temporary variable, thus passing
the absolute value of the input to bsloww1.  This caused #16623.

This fix undoes the incorrect change.

392dd2de03 Consolidate code to compute sin and cos from lookup tables
This patch consolidates the multiple copies of code that looks up sin
and cos of a number from the lookup table and computes the final
value, into static functions.  This does not have a noticeable
performance impact since the functions are inlined by gcc.

There is further scope for consolidation in the functions but they
cause a more noticable impact on performance (>5%) due to which I have
held back on them.

84ba214c21 Remove more redundant computations in s_sin.c
Removed more redundant computations in the slow paths of the sin and
cos functions.  The notable change is the passing of the most
significant bits of X to the slow functions to check if X is positive
so that just the absolute value of x can be passed and the repeated
ABS() operation is avoided.

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.
