Devin Coughlin 684d19d879 Revert "Revert "[analyzer] Make MallocChecker more robust against custom redeclarations"" 
This reverts commit r284340 to reapply r284335. The bot breakage was due to
an unrelated change in the polybench test suite.

Devin Coughlin eeb8d20db4 Revert "[analyzer] Make MallocChecker more robust against custom redeclarations" 
This reverts commit r284335.

It appears to be causing test-suite compile-time and execution-time
performance measurements to take longer than expected on several bots.
This is surprising, because r284335 is a static-analyzer-only change.

Devin Coughlin 62ce463a35 [analyzer] Make MallocChecker more robust against custom redeclarations 
Add additional checking to MallocChecker to avoid crashing when memory
routines have unexpected numbers of arguments. You wouldn't expect to see much
of this in normal code (-Wincompatible-library-redeclaration warns on this),
but, for example, CMake tests can generate these.

This is PR30616.
