2018-09-14Rollup merge of #53950 - michaelwoerister:more-lto-cli, r=alexcrichtonkennytm-2/+1
Allow for opting out of ThinLTO and clean up LTO related cli flag handling. It turns out that there currently is no way to explicitly disable ThinLTO (except for the nightly-only `-Zthinlto` flag). This PR extends `-C lto` to take `yes` and `no` in addition to `thin` and `fat`. It should be backwards compatible. It also cleans up how LTO mode selection is handled. Note that merging the PR in the current state would make the new values for `-C lto` available on the stable channel. I think that would be fine but maybe some team should vote on it.

2018-07-31rustc: Handle linker diagnostic from LLVMAlex Crichton-2/+10
Previously linker diagnostic were being hidden when two modules were linked together but failed to link. This commit fixes the situation by ensuring that we have a diagnostic handler installed and also adds support for handling linker diagnostics.

2018-07-18rustc: Remove a workaroudn in ThinLTO fixed upstreamAlex Crichton-14/+0
This commit removes a hack in our ThinLTO passes which removes available externally functions manually. The [upstream bug][1] has long since been fixed, so we should be able to rely on LLVM natively for this now! [1]: https://bugs.llvm.org/show_bug.cgi?id=35736

2018-06-12Rename -Z no-verify to -Z verify-llvm-irNikita Popov-2/+2
This disables IR verification by default.
2018-06-12Respect -Z no-verify during LTONikita Popov-6/+11
Currently -Z no-verify only controls IR verification prior to LLVM codegen, while verification is performed unconditionally both before and after linking with (Thin)LTO.
