Description:
This is used to provide a accurate implementation for trigonometric functions
used in V8.

Local Modifications:
For the use in V8, fdlibm has been reduced to include only sine, cosine and
tangent.  To make inlining into generated code possible, a large portion of
that has been translated to Javascript.  The rest remains in C, but has been
refactored and reformatted to interoperate with the rest of V8.
