Remove `librustc_ast` session globals By moving the data onto `Session`. r? @petrochenkov

Eliminate the `SessionGlobals` from `librustc_ast`.

2020-08-08T02:03:42+00:00

By moving `{known,used}_attrs` from `SessionGlobals` to `Session`. This means they are accessed via the `Session`, rather than via TLS. A few `Attr` methods and `librustc_ast` functions are now methods of `Session`. All of this required passing a `Session` to lots of functions that didn't already have one. Some of these functions also had arguments removed, because those arguments could be accessed directly via the `Session` argument. `contains_feature_attr()` was dead, and is removed. Some functions were moved from `librustc_ast` elsewhere because they now need to access `Session`, which isn't available in that crate. - `entry_point_type()` --> `librustc_builtin_macros` - `global_allocator_spans()` --> `librustc_metadata` - `is_proc_macro_attr()` --> `Session`

mir: `unused_generic_params` query

2020-07-20T18:35:30+00:00

This commit implements the `unused_generic_params` query, an initial version of polymorphization which detects when an item does not use generic parameters and is being needlessly monomorphized as a result. Signed-off-by: David Wood

debuginfo: add type metadata for params

2020-07-20T10:23:31+00:00

This commit adds type metadata for generic parameters (that arise from polymorphization). Generic parameter metadata is considered zero-sized and named after the generic parameter. Signed-off-by: David Wood

debuginfo: no type metadata if substs reqd

2020-07-20T10:23:29+00:00

This commit skips generating debuginfo type metadata if substitutions are required by the type. This avoids ICEs that result from layouts of types with substitutions being computed. Signed-off-by: David Wood
