5bdc56c00c Add a new ABI to support cmse_nonsecure_call 
This commit adds a new ABI to be selected via `extern
"C-cmse-nonsecure-call"` on function pointers in order for the compiler to
apply the corresponding cmse_nonsecure_call callsite attribute.
For Armv8-M targets supporting TrustZone-M, this will perform a
non-secure function call by saving, clearing and calling a non-secure
function pointer using the BLXNS instruction.

See the page on the unstable book for details.

02e1fd48d1 Rollup merge of #81618 - bjorn3:sync_cg_clif-2021-02-01, r=bjorn3 
Sync rustc_codegen_cranelift

The highlight of this sync are abi compatibility with cg_llvm allowing mixing of cg_clif and cg_llvm compiled crates and switching to the x64 cranelift backend based on the new backend framework.

2b8f2acd5f Indicate both start and end of pass RSS in time-passes output 
Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.

Also, improve alignment of columns.

e67b72de2e Rollup merge of #81333 - RalfJung:const-err-simplify, r=oli-obk 
clean up some const error reporting around promoteds

These are some error reporting simplifications enabled by https://github.com/rust-lang/rust/pull/80579.

Further simplifications are possible but could be blocked on making `const_err` a hard error.

a921a476c8 Auto merge of #79945 - jackh726:existential_trait_ref, r=nikomatsakis 
Move binder for dyn to each list item

This essentially changes `ty::Binder<&'tcx List<ExistentialTraitRef>>` to `&'tcx List<ty::Binder<ExistentialTraitRef>>`.

This is a first step in moving the `dyn Trait` representation closer to Chalk, which we've talked about in `@rust-lang/wg-traits.`
