For both amd64 and arm, when ICF (Identical Code Folding) is enabled,
there is >60,000 drop in the number of unique addresses of text symbols.
We check here that the drop is at least 10,000.
See https://crbug.com/813272#c18 for details.

This CL updates the whitelist for debug_info_test stage, when checking
whether DebugInfo session exists or not.
We do not care about the debug info in autotest, so whitelisted this
directory.

This patch introduces two tests, one to check whether debug info section
exists in the elf file, the other to check whether DW_AT_producer exists
in each compile unit of debug info.

There are still a few release builders that are not passing the

capri-release, cobblepot-release, guado-macrophage-release,
lakitu-nc-release, lakitu-st-release, lasilla-ground-release,
lassen-release, macchiato-release.

We found a few more packages/files that need to be built with
GCC and are adding them to our debug_info_test whitelists.
BUG=chromium:813268
TEST=Tested with remote tryjobs: lakitu-release, gale-release,
rainier-release, beaglebone-relase, fizz-release, cave-release.
All passed the DebugInfoTest stage.

The debug_info_test stage verifies that everything that is supposed
to be built with LLVM is actually being built with LLVM. We have
to whitelist a few files/packages that must continue to be built
with GCC. This CL updates the whitelists to make this stage pass
on AMD64.
BUG=chromium:817648
TEST= debug_info_test.py passed on my local terra build, with these
changes. DebugInfoTest stage passed on cros tryjob fizz-llvm-toolchain-tryjob.
