Check for specific error messages in the testsuite. This permits testing that the compiler emits error messages for specific lines that match egrep regexps. The desired error messages are expressed using comments of the form // ERROR "regexp" R=r DELTA=90 (73 added, 8 deleted, 9 changed) OCL=15513 CL=15566 2008-09-19 21:39:49 +00:00			`if i33 == (1<<64) -1 { // ERROR "overflow"`
