Late parsing (in contrast to template instantiation) is sensitive to the pragma

Increment and decrement are equivalent to adding or subtracting 1. For the
floating-point values these operations depend on the current rounding mode.

`fast-math` also does not have clear semantics. It is however used to express
user's expectations that some assumptions are valid. `optnone` could also be
treated from similar vi
