lang/rust: Update to 1.34.0

[tobik]

Summary

https://internals.rust-lang.org/t/rust-1-34-0-pre-release-testing/9785

Patch without renames that might be easier to apply: https://people.freebsd.org/~tobik/patches/rust-1.34.0.diff

Test Plan

Lots of patches did not apply cleanly, so this is probably incomplete.
A test build on amd64 is still in progress.

@pkubaj_riseup.net @mikael.urankar_gmail.com We need new bootstraps for (and testing on) arm* and powerpc64. Can you help with that?

[tobik]

• Put back %CC% in a couple of patches

[jbeich]

• bundled rustc-ap-syntax in devel/racer is very picky, so updating the port to later version maybe required (e.g., latest unless it depends on rust 1.35)
• textproc/ripgrep/files/patch-no-bitmask can be dropped

[tobik]

• Fix bootstrap.py patch
• Add crate:: to rustc-ap-rustc_target armv* patches too
• Drop textproc/ripgrep/files/patch-no-bitmask

[tobik]

• Hopefully unmark files/patch-src_bootstrap_bootstrap.py as deleted now

• Fix post-install when restarting failed builds and recursively delete share/doc/rust/*.old
• Add arm*, powerpc64 bootstraps

That should do. I've mirrored them in LOCAL/tobik. Thanks!

[tobik]

• Update and fix build of devel/racer

scope-tls comment above is obsolete since 1.0.0 but RUSTC_BOOTSTRAP=1 is still required by rustc-ap-syntax (and its dependecies). Either update the comment or remove it.

[tobik]

• racer: remove obsolete comment

[tobik]

Builds on 13.0/amd64, 12.0/amd64 and 11.2/i386 were all fine.

Anybody testing arm*, powerpc64?
