Change the clang driver with the use of -no-integrated-as for darwin to use
the -Q flag to the as(1) assembler driver.

We will soon be switching the darwin as(1) assembler driver to call clang(1)
and use the intergated assembler by default.  To do this and still support
clang(1)'s -no-integrated-as flag, when clang(1) runs the as(1) assembler
driver and -no-integrated-as is used it needs to pass the -Q flag to as(1)

integrated assembler.

10 years ago[analyzer] Silence warnings coming from allocators used by std::basic_string.
Jordan Rose [Fri, 15 Nov 2013 02:11:19 +0000 (02:11 +0000)]
[analyzer] Silence warnings coming from allocators used by std::basic_string.

This is similar to r194004: because we can't reason about the data structure
invariants of std::basic_string, the analyzer decides it's possible for an
allocator to be used to deallocate the string's inline storage. Just ignore
this by walking up the stack, skipping past methods in classes with
"allocator" in the name, and seeing if we reach std::basic_string that way.
