…arts of the compiler
`cfg_select!` parsing needs to be implemented in rustfmt right now because there's no good way to call `rustc_attr_parsing::parse_cfg_select`.
The plan is to leverage `rewrite_match_body` to help with `cfg_select!` formatting.
This allows a per-target `override-allocator` to revert to the system allocator even if there is a global rule specifying a different allocator. Remap `jemalloc = false` to `override-allocator = "system"` instead of mapping it to "override-allocator is unset"; this restores the correct precedence behaviour of this setting. This also allows `Config::override_allocator()` to always resolve the directive to a definite value, rather than needing it to be wrapped in an `Option`, which simplifies some other code. Finally, print a more specific warning when `jemalloc` is set, telling users the appropriate setting to use for `override-allocator` depending on whether `jemalloc` is set to true or false.
