found in unwind info)

Corresponds to -fno-unwind-tables (usually default in gcc).

The problem is that some clients of gcc lookout at the stdout output of gcc;
this requires that all the analyzer diagnostics go to stderr to avoid polluting

needs to be fixed here - a previous commit made sure
that intrinsics always get the right attributes.
So remove no-longer needed code, and while there use
Intrinsic::getDeclaration rather than getOrInsertFunction.

be i8*, was an array*).
