rustc: Add `-C lto=val` option This commit primarily adds the ability to control what kind of LTO happens when rustc performs LTO, namely allowing values to be specified to the `-C lto` option, such as `-C lto=thin` and `-C lto=fat`. (where "fat" is the previous kind of LTO, throw everything in one giant module) Along the way this also refactors a number of fields which store information about whether LTO/ThinLTO are enabled to unify them all into one field through which everything is dispatched, hopefully removing a number of special cases throughout. This is intended to help mitigate #47409 but will require a backport as well, and this would unfortunately need to be an otherwise insta-stable option. 2018-01-16 17:02:31 -06:00			`// compile-flags: -Clto=fat`
