Compiling rustc 1.43.0 with local LLVM 10 fails

[dilyanpalauzov]

I call

./configure --enable-parallel-compiler --enable-optimize --llvm-root=/usr/local --enable-extended --enable-llvm-link-shared --enable-local-rust
/src/rustc-1.43.0-src/x.py  build 

and the system says:

DEBUG = Some("false")
CARGO_CFG_TARGET_FEATURE = Some("fxsr,mmx,sse,sse2")

Indeed /usr/local/include/llvm/Support/TimeProfiler.h:timeTraceProfilerInitialize does require parameters.

LLVM 10 is not yet supported (see https://github.com/rust-lang/rust/pull/67759). It shouldn't be hard to land that change without the LLVM 10 upgrade though.

The necessary changes landed in #70163. For 1.43, you can use the patch I applied to Fedora: https://src.fedoraproject.org/rpms/rust/blob/dd62b3568394ee83ca9b47089b30489e46af6cf2/f/rust-pr70163-prepare-for-llvm-10-upgrade.patch

I will retry with LLVM 10 on rust 1.44.
