COMP: remove extraneous cast to double

The constant is already the output type of the function, no casting is
needed.

BUG: Same test function in different file causes conflict

Having the same templated function name in multiple test file for the
same executable can cause the symbols to be mixed up. This patch
addresses a number of TIFF failing tests on OSX with genuine gcc 4.2.

ENH: Add RegularStep gradient optimizer to ITKv4

We probably do not need this optimizer technically; however, having such
an optimizer is the preliminary step to convert "ImageRegistration1"
example to ITKv4.

Using ordinary GradientDescentOptimizerv4 does not provide convergence
for the example 1. Also, the results generated by other v4 optimizers
(e.g. GradientDescentLineSearchOptimizerv4) show a very fast
convergence, and they are not suitable for graphical interpretation of
the registration process that is necessary for the educational purposes.
