This pass is used after Typing for ensuring that some expressions have
an expected type.
Typically, we use this pass for cheking if an expression after a [do]
has the type [void].
In case the expression has not the given type, the pass_WarnCoerce raise
a warning of the class typer.warncoerce. This class can be turned on --warn-error.
The directives is keeped, it will be removed in the PurgeTyperDirective pass,
with the other typer directives.
