math_brute_force: Factor out GetUnaryKernel and GetBinaryKernel (#1525)

Browse Source 
Use common functions to create the kernel source code for testing
1-argument and 2-argument math builtins.  This reduces code duplication.

Use appropriate patterns to initialise variables to their full bit
widths.  For example, `0xdead` was previously used to initialise 32-bit
integers, while now a larger number spanning all bytes is used.
