Use -DUSE_MAX macro instead of -UUSE_MIN.

As described here: #2420 (comment)
I'm suggesting to come up with more robust macro usage. So far, I've converted USE_MIN macro usage. The patch exposes one more issue in the current CMake files:

GenerateNamedObjects("${KERNELDIR}/${I${float_char}MINKERNEL}" "" "i*min_k" false "" "" false ${float_type})

there's missing USE_MIN macro.

@martin-frbg What do you think about the suggested approach?

[martin-frbg]

I'm not yet convinced that it is worth the trouble to change lots of existing files (with the risk of missing one), just to replace a "negative" define with the equivalent "positive" one. For new files, your suggestion to #error out if none of the possible options was seen is certainly superior but I feel that retroactively changing the logic will just make diffs harder to follow.

Alright, I understand that the changes will be quite invasive.
