This commit removes the crates.io dependency of
rustc-demangle
fromrustc_codegen_llvm
. This crate is actually already pulled in to partof the
librustc_driver
build and with the upcoming pipeliningimplementation in Cargo it causes build issues if
rustc-demangle
isleft to its own devices.
This is not currently required, but once pipelining is enabled for
rustc's own build it will be required to build correctly.
