Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

[analyzer] StdLibraryFunctions: provide platform-specific function summaries.
...
Because standard functions can be defined differently on different platforms,
this commit introduces a method for constructing summaries with multiple
variants, whichever matches better. It is also useful for supporting overloads.

[analyzer] Add StdLibraryFunctions checker.
...
This checker does not emit reports, however it influences the analysis
by providing complete summaries for, or otherwise improving modeling of,
various standard library functions.
This should reduce the number of infeasible paths explored during analysis.
The custom function summary format used in this checker is superior to
body farms by causing less unnecessary state splits,
which would result in better analysis performance.
