Add DIAG_OFF_FLEX and DIAG_ON_FLEX for use in Flex scanners.
DIAG_OFF_FLEX turns off all warnings that we want to disable for
Flex-generated code due to some versions of Flex generating code that
triggers those warnings.
DIAG_ON_FLEX restores those warnings, so we do the checks for code that
*we* wrote.
Use them in .l files.
