M109.0.5414.120

This is a copy of the release in Thorium-Win

• Special Windows 7/8/8.1 release! (Not only for these platforms, but see below.)
• M109 Maintenance release.
• HEVC patch updated.
• Icon updated for Linux and Windows, which removes the padding on the outside of the thorium logo to match
  upstream change, the only effect is that the logo is slightly bigger.
• More LLVM optimization flags
• Removed the "unsupported OS" infobar banner for Win7/8/8.1 and Ubuntu 16.04, Debian 9, and Arch<2018.12

NOTE: Going forward, Thorium will be built to more stable versions. This one is based on M109 stable (see below), future versions will be based on the equivalent of "beta" or "dev" channel, rather than tip-o-tree, i.e. "canary" channel.

IMPORTANT M109 is the last version of Chromium for Windows 7, Windows 8, and Windows 8.1 😢 as per Here. I still use and enjoy Windows 7, and so have made a site for it here > https://thorium.rocks/win7 This is why this release is based on stable M109. I will be updating the links on my win7 page to link to these. Another deviation from standard Thorium releases, is that the windows 7 release will have a special 32 bit SSE2 build for old computers, on top of the SSE3, AVX, and AVX2 builds. There is also a small easter egg on the chrome://version page, to show love for one of Micro$oft's greatest OSes, back when that $ sign was a little smaller, lol.

M109 will also be getting maintenance releases for the Win7/8/8.1 version, tracking the official chrome stable versions as per https://chromiumdash.appspot.com/releases?platform=Windows and I will be attempting to backport patches from M110 into M109, as time and knowledge permits.
