When compiled with gn argument 'is_debug=false' these tests fail on
Windows due to the fact that they're compiled with '/guard:cf'.

This CL changes the use of FUNCTION_CAST to GeneratedCode::Call which
contains DISABLE_CFI_ICALL attribute. This is analogous to how
assembled functions are called in Assembler tests for other
architectures.
