Disable dtor inlining for clang-tidy
LLVM r328258 turned on a feature called temporary dtor inlining by
default for all of C++ in clang-tidy. This feature appears to be
somewhat over-aggressive when objects are being passed by value. For
example, given:
void foo(std::unique_ptr<int> i);
void bar() {
auto x = std::make_unique<int>();
int *i = x.get();
foo(std::move(x));
*i = 99;
}
...clang-tidy will complain about `*i = 99;` being a definite
use-after-free. This is incorrect, however: `foo` could stash the
`unique_ptr` it's given in a global, or a class member, or ...
Until upstream fixes this bug, it's probably best to keep this disabled.
Bug: None
Test: Ran the analyzer across Android locally. Nothing broke; number of
complaints dropped significantly.

This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
