Don't inline methods whose basic blocks end with a throw
If the basic block will end up throwing, it is commonly not in the
critical path. If we throw, we incur in a performance cost anyway
so we can skip inlining those methods. Additionally, methods
before a throw are sometimes construct information which is
something we are not interested in inlining.
Note that this CL doesn't stop inlining for methods that eventually
always end with a throw. See the 2243- test for an example
(testEndsWithThrowButNotDirectly). We could perform a more detailed
analysis but that analysis will increase compile time so it is left
as a further optimization if needed.
Locally in a Pixel 5 with AOSP, code size improved:
* AGSA: 15.3 MB (~4.6%)
* System Server: 1.9 MB (~3.74%)
* SysemUIGoogle: 0.88MB (~3.05%)
