Add minimal-runtime support for integer overflows.

Browse Source 
Adds Soong support for -fsanitze-minimal-runtime when using
the integer overflow sanitizers. This makes the crashes due to these
sanitizers less mysterious.

Test: Compiled and checked the generated compiler commands
Test: Checked program that overflows for the abort reason
