The standard library uses `_precondition` calls which have a message argument. Allow disabling the generated cond_fail by these message arguments. For example: _precondition(source >= (0 as T), "Negative value is not representable") Results in a `cond_fail "Negative value is not representable"`. This commit allows for specifying a file that contains these messages on each line. /path/to/disable_cond_fails: ``` Negative value is not representable Array index is out of range ``` The optimizer will remove these cond_fails if the swift frontend is invoked with `-Xllvm -cond-fail-config-file=/path/to/disable_cond_fails`.
