73b5b0775a [poincare] Avoid nullptr context on non-Numbers sign and nullStatus methods

5df60e946a [poincare] shallowBeautify can modify the reduction context 
UnitConvert must set UnitConversion to None, otherwise the unit asked
for in the conversion might get changed after being properly set in
UnitConvert::shallowBeautify.

c92b770112 Performance fixes relating to floating point constants 
This replaces unnecessary double-precision soft-float operations with
single-precision floating-point operations, mainly by casting.

In a couple places I also replace a function call with a constant.

a34ecd2769 [poincare] Use std::move when needed 
When returning a subclass of an Expression as an Expression, make sure
to use std::move, otherwise the compiler cannot proceeed to copy
ellision.

6948de2ad3 [poincare] ComplexCartesian: fix approximation 
The assertions that the real and imaginary parts are real can be false
due to double lack of precision. We escape these cases by returning an
undefined approximation.

c6039423a9 [poincare] When simplifying an expression, also compute the approximation from the reduced 
expression to avoid loss of precision.

If an expression is reduced to a ComplexCartesian(a, b), we compute the
approximation from ComplexCartesian(a,b) instead of going through the
potentially complicated expression resulting from beautifying
(sqrt(a^2+b^2)*exp(i*(arctan(b/a) -Pi/2*sign(b)) for example)
