min16float is not required to convert its input to an 16-bit float.
Instead, use f32tof16, and f16tof32.
This is also required to be able to enable the IEEE strictness option on
FXC, otherwise FXC emits an error X4028: expression has a minimum
precision type and cannot be marked precise

It appears that FXC and DXC do some validation post dead-code-elimination.
These tests have been updated so that the return value is assigned to a storage buffer, ensuring that all validation is performed.
Many DXC tests are affected by https://github.com/microsoft/DirectXShaderCompiler/issues/5082, which have been SKIP'ed.
