  fix Issue 20730 - [REG 2.091] __traits(compiles) fails if any ungagged errors
occurred in compilation

  When running semantic on __traits(compiles), errors are gagged, so
  the saved errors count is global.gaggedErrors, and not global.errors.

  So the condition always evaluated as true if any real errors occured
  during compilation, and every subsequent __traits(compiles) errors too,
  whether it is valid syntax or not.
