Add support for a "strict" floating-point mode (#709)
This change adds an API function and command line options for controlling the default floating-point behavior for a target, with options for "fast" and "precise" computation.
The "precise" option gets mapped to the "IEEE strictness" mode in `fxc` and `dxc` (there is currently no equivalent option for glslang that I could find).
