r=RalfJung [Miri] Use a session variable instead of checking for an env var always In CTFE heavy code, checking the env var everytime is inefficient. We can do a lot better by using a `Session` variable instead. r? @RalfJung Part of #69297

2020-03-10[Miri] Use a session variable instead of checking for an env var alwaysWesley Wiser-13/+20
In CTFE heavy code, checking the env var everytime is inefficient. We can do a lot better by using a `Session` variable instead.

2020-03-10Auto merge of #66364 - Centril:cleanup-macro-def, r=petrochenkov,eddybbors-10/+5
Cleanup `rmeta::MacroDef` Avoid using rountrip parsing in the encoder and in `fn load_macro_untracked`. The main reason I was interested in this was to remove `rustc_parse` as a dependency of `rustc_metadata` but it seems like this had other benefits as well. Fixes #49511. r? @eddyb cc @matthewjasper @estebank @petrochenkov
2020-03-10Store `TokenStream` in `rmeta::MacroDef`.Mazdak Farrokhzad-10/+5
This removes a hack from `load_macro_untracked` in which parsing is used.

2020-03-10Rollup merge of #69475 - Zoxc:no-no-force, r=michaelwoeristerMazdak Farrokhzad-185/+140
Remove the `no_force` query attribute This removes the `no_force` query attribute and instead uses the `DepNodeParams` trait to find out if a query can be forced. Also the `analysis` query is moved to the query macro. r? @eddyb

2020-03-09Rollup merge of #69762 - RalfJung:validity-errors, r=oli-obkMazdak Farrokhzad-4/+23
Ensure that validity only raises validity errors For now, only as a debug-assertion (similar to const-prop detecting errors that allocate). Now includes https://github.com/rust-lang/rust/pull/69646.

2020-03-08Rollup merge of #69326 - JOE1994:os_str_widestring, r=RalfJungMazdak Farrokhzad-0/+10
mir-interpret: add method to read wide strings from Memory Implemented *step2* from [instructions](https://github.com/rust-lang/miri/issues/707#issuecomment-561564057) laid out in rust-lang/miri#707. Added 2 new methods to struct `rustc_mir::interpret::InterpCx`. * `read_os_str_from_wide_str` (src/librustc_mir/interpret/operand.rs) * `write_os_str_to_wide_str` (src/librustc_mir/interpret/place.rs) - used existing logic implemented in [MIRI/src/eval.rs](https://github.com/rust-lang/miri/blob/94732aaf7bf79fd01a4a48d11155c6586b937514/src/eval.rs#L132-L141) These methods are intended to be used for environment variable emulation in Windows.
