ppcfpopcodes: Fix load float.

Type casting an int to a float assigns the value of the int to the float which is not what is needed here.

Clean up #includes
...
Result of running IWYU (https://include-what-you-use.org/ ) and
applying most of the suggestions about unncessary includes and
forward declarations.
Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.
