libcompiler-rt.a is dead, long live libcompiler-builtins.rlib This commit moves the logic that used to build libcompiler-rt.a into a compiler-builtins crate on top of the core crate and below the std crate. This new crate still compiles the compiler-rt instrinsics using gcc-rs but produces an .rlib instead of a static library. Also, with this commit rustc no longer passes -lcompiler-rt to the linker. This effectively makes the "no-compiler-rt" field of target specifications a no-op. Users of `no_std` will have to explicitly add the compiler-builtins crate to their crate dependency graph *if* they need the compiler-rt intrinsics. Users of the `std` have to do nothing extra as the std crate depends on compiler-builtins. Finally, this a step towards lazy compilation of std with Cargo as the compiler-rt intrinsics can now be built by Cargo instead of having to be supplied by the user by some other method. closes #34400
