Artem Dergachev f2192b204f [analyzer] RetainCount: A function isn't a CFRetain if it takes no arguments. 
Don't crash when a function has a name that starts with "CF" and ends with
"Retain" but takes 0 arguments. In particular, don't try to treat it as if
it returns its first argument.

These problems are inevitable because the checker is naming-convention-based,
but at least we shouldn't crash.

Just use one single entry point, since we have AnyCall utility now.

Bruno Cardoso Lopes bb3b7cff96 Revert "[analyzer] [NFC] Split up RetainSummaryManager from RetainCountChecker" 
This reverts commit a786521fa66c72edd308baff0c08961b6d964fb1.

Bots haven't caught up yet, but broke modules build with:

../tools/clang/include/clang/StaticAnalyzer/Checkers/MPIFunctionClassifier.h:18:10:
fatal error: cyclic dependency in module 'Clang_StaticAnalyzer_Core':
Clang_StaticAnalyzer_Core -> Clang_Analysis ->
Clang_StaticAnalyzer_Checkers -> Clang_StaticAnalyzer_Core

George Karpenkov 0ac54fad53 [analyzer] [NFC] Split up RetainSummaryManager from RetainCountChecker 
ARCMigrator is using code from RetainCountChecker, which is a layering
violation (and it also does it badly, by using a different header, and
then relying on implementation being present in a header file).

This change splits up RetainSummaryManager into a separate library in
lib/Analysis, which can be used independently of a checker.
