Erik Eckstein 388bc31ba7 Add a nothrow flag to the SIL apply_inst. ...

If the compiler can prove that a throwing function actually does not throw it can
replace a try_apply with an "apply [nothrow]". Such an apply_inst calls a function
with an error result but does not have the overhead of checking for the error case.

Currently this flag is not set, yet.
