Fix storing of non-float SPIR-V constants

Reactor Float scalar and vector constants may not fully preserve the
bit pattern of the values they were constructed from. Specifically,
signaling NaN values (sNaN) may become quiet NaN values (qNaN). Thus
they should not be used for storing SPIR-V constant objects to memory.
Interpret the data as integer instead. Note Object::constantValue is
already a uint32_t array.
