Description:
THD has a bool member called no_errors.
It is used only by the range optimizer, to ignore certain
conversion errors during optimization.

The value is checked in various val_xxx functions
and warnings are suppressed.

A better solution is to use an Internal_error_handler in the range optimizer.

How to repeat:
Read the code.

Suggested fix:
See description.

Fixed in 5.8.0.

Code cleanup. No changelog entry needed.
