Build Swift for x86 Android (also to support Android Emulator)

Motivation
At the moment we can only build for armv7a
. While this covers the great proportion of Swift devices on the market today, it'd be great to build for x86 devices as well for two main reasons:
- x86 Devices make up about 10% of the total Android market, which is about 200 million devices.
- The Android Emulator only really works with x86-built libraries. The ARM CPU emulation is so slow that it's basically unusable. This isn't a huge issue, but would be interesting particularly for things like automated tests.
Proposed solution
"Somebody" needs to make a PR on Apple's Swift repo adding support for Android x86. I suspect this won't be anywhere near as involved as the original port, but it would be a non-trivial piece of work that as far as I know has not been attempted yet.
Potential alternatives
- Wait for x86 devices to lose market share (if this happens to be the trend over time?)

An update on this: x86 support is "done". We currently have a toolchain that builds for x86_64 at least, which is enough to support the Android Emulator at full speed. I will leave this Issue open until we update swift-android-toolchain
with updated instructions
