The C++ standard allows constexpr variables declared with the extern
keyword to have external linkage. Previously MSVC wasn't abiding by
this. This just makes the compiler more standards compliant during
builds.

Given we currently don't make use of anything that would break by this,
this is safe to enable.

Makes it much nicer to visually scan the options. This also starts the
flag descriptions from the same column for the same reason.

Unintentionally introduced in 552d5071

Port citra-emu/citra#3839: "travis: use prebuilt image"

gl_shader_disk_cache: Improve precompiled shader cache generation speed and size

shader_ir: Miscellaneous fixes

kernel/vm_manager: Remove usages of global system accessors

video_core: Silent -Wswitch warnings

Corrections on Half Float operations: HADD2 HMUL2 and HFMA2

kernel/svc: Clean up wait synchronization related functionality

Allow picking a Compatibility Profile for OpenGL.

Port citra-emu/citra#4748: "Launch directly in Mac without terminal"

applets: Add AppletManager and implement PhotoViewer and Error applets

CMakeLists: Ensure we specify Unicode as the codepage on Windows

gl_state: Fix samplers memory corruption

Fix flipping on some games by applying Y direction register

gl_shader_decompiler: Disable variable AOFFI on unsupported devices

service/audctl: Implement GetTargetVolumeMin() and GetTargetVolumeMax()

Support compressed formats on linear textures.

GPU Manager: Implement ReadBlockUnsafe and WriteBlockUnsafe

Implement Kepler Memory on both Linear and BlockLinear.

Do some corrections in conversion shader instructions.

This option allows picking the compatibility profile since a lot of bugs
are fixed in it. We devs will use this option to easierly debug current
problems in our Core implementation.:wq

shader_ir/decode: Miscellaneous fixes to half-float decompilation

kernel/wait_object: Make GetHighestPriorityReadyThread() a const member function

yuzu/bootmanager: Resolve constructor initializer list warnings

kernel/svc: Name supervisor call 0x36

core: Reorganize boot order

It was possible for "samplers" to be read without being written. This
addresses that.
