There are three possible cases for binary location in Chromium:
1. The binary is a standalone executable or dynamic library in the product
dir, the debug info is in "binary.dSYM" in the product dir.
2. The binary is a standalone framework or .app bundle, the debug info is in
"Framework.framework.dSYM" or "App.app.dSYM" in the product dir.
3. The binary is a framework or an .app bundle within another .app bundle
(e.g. Outer.app/Contents/Versions/1.2.3.4/Inner.app), and the debug info
is in Inner.app.dSYM in the product dir.
The first case is handled by llvm-symbolizer, so we only need to construct
.dSYM paths for .app bundles and frameworks.
We're assuming that there're no more than two nested bundles in the binary
path. Only one of these bundles may be a framework and frameworks cannot
contain other bundles."""
