rustc: Update LLVM with a ThinLTO fix

alexcrichton · alexcrichton · commit a2aba791f1c3 · 2017-10-11T09:10:59.000-07:00
This commit updates LLVM with a patch that's landed upstream to fix an assertion that was tripping when ThinLTO was activated. Unfortunately I wasn't able to get a reduced test case, but I've tested manually on the affected crates and the assertion is indeed fixed. Closes #45131
