Pull Request Overview
This PR simplifies the UncontrolledProcessOperation.ql query by removing redundant code that was checking for process operation arguments using both direct and indirect expression patterns. The change eliminates duplication by keeping only the asIndirectExpr() method, as having both methods doesn't change the query results and was a leftover from earlier porting work.
Key Changes
- Removed redundant expression matching pattern in process operation detection
- Simplified argument matching to use only indirect expressions

Having both
asExpr()andasIndirectExpr()doesn't appear to change any results. This was a leftover from back when we ported the default-taint-tracking queries over, and we still had a few remaining bugs inasExprandasIndirectExpr, and probably some remaining pointer sources that needed to be converted to pointee sources.I've manually verified that all the removed results from DCA are due to deduplication.
