Add sin(), cos() and sqrt() to std.complex
...
This also requires std.math.coshisinh() to be accessible to std.complex,
so I changed its protection attribute to "package".

denormalizedException -> subnormalException
...
The term "denormal" is deprecated by IEEE, and should be replaced by
"subnormal" in all cases. Fix all the comments to make sure this confusion
doesn't happen again.

IEEE exceptions and status flags are properties
...
They are all global properties of the processor, so it makes a lot of sense
for them to look like global variables.

Add denormalizedException
...
The denormalizedException is set whenever a denormalized value is
manipulated or created. It is useful to know that denormalized values
are generated because it indicates that precision is low.
Further performance of denormalized number can be up to 100 times slower
even when handled in hardware (see Table 2 in "Quantifying the
Interference Caused by Subnormal Floating-Point Values" by Isaac Dooley
and Laxmikant Kale).

Remove the "NotImplemented" exception, and turn it into a simple assert. This allows all functions to be marked as nothrow. I have marked them all as @safe/@trusted as well.

D implementation of pow(), avoiding dependence on C. The big benefit is that pow() is now pure, but also improved accuracy of corner cases.
...
All math functions are now @safe or @trusted, and all are pure nothrow except where implemented by C functions.
