c07d1e2f88 Use same --remap-path-prefix as bootstrap for testing the rustc test suite 
This allows removing the CFG_VIRTUAL_RUST_SOURCE_BASE_DIR hack and
re-enabling a fair amount of tests.

e5197cf1de Switch the build system from super:: to crate:: 
This was a left over from when build_system/main.rs was at ./y.rs.

0b3060138b Use -Zinline-mir instead of -Zmir-opt-level=3 
Except for mir inlining all mir opts that are beneficial for cg_clif now
run on -Zmir-opt-level=2. -Zmir-opt-level=3 enables some more expensive
optimizations.

d0b8896189 Allow building the build system using cargo 
Rust's build system only handles cargo, not rustc.

5b3bc29008 Allow testing a cranelift backend built into rustc itself 
This avoids building cranelift twice in rust's CI and is a lot easier
than trying to make building of codegen backends work from within a
cargo invocation done by rust's build system.

a2f720d9fe Allow building and testing without rustup 
This can be done by installing the nightly specified in
rust-toolchain.toml and then pointing the CARGO, RUSTC and RUSTDOC env
vars to the right executables.

98ddd69aae Add wrappers to dist/bin/ too in addition to dist/ 
Rust's build system since recently expects rustc to be in a bin/
directory if it is specified using the rustc option in config.toml.

0f4df8fb0e Eliminate a couple of extra calls 
This is an additional 17% improvement on ./y.rs compile --sysroot none

Benchmark 1: ./y_before.bin build --sysroot none
  Time (mean ± σ):      1.533 s ±  0.022 s    [User: 1.411 s, System: 0.471 s]
  Range (min … max):    1.517 s …  1.589 s    10 runs

Benchmark 2: ./y_after.bin build --sysroot none
  Time (mean ± σ):      1.311 s ±  0.020 s    [User: 1.232 s, System: 0.428 s]
  Range (min … max):    1.298 s …  1.366 s    10 runs

Summary
  './y_after.bin build --sysroot none' ran
    1.17 ± 0.02 times faster than './y_before.bin build --sysroot none'

abcff71bec Significantly speed up assembling of sysroots 
By avoiding some redundant rustc calls and stripping debuginfo for
wrappers. ./y.rs build --sysroot none now runs 44% faster.

Benchmark 1: ./y_before.bin build --sysroot none
  Time (mean ± σ):      2.200 s ±  0.038 s    [User: 2.140 s, System: 0.653 s]
  Range (min … max):    2.171 s …  2.303 s    10 runs

Benchmark 2: ./y_after.bin build --sysroot none
  Time (mean ± σ):      1.528 s ±  0.020 s    [User: 1.388 s, System: 0.490 s]
  Range (min … max):    1.508 s …  1.580 s    10 runs

Summary
  './y_after.bin build --sysroot none' ran
    1.44 ± 0.03 times faster than './y_before.bin build --sysroot none'
