Why we need to special-case ccache | sccache here?

Unfortunately cc-rs isn't the most general either :(

So to me it seems like both places are somewhat wrong - and would be nice to fix. I install sccache locally and it would ideally be supported by path too. To be specific, I configure sccache = "/some/path/sccache" which we should probably support here... And eventually in cc too.

I'll leave a comment saying how to fix this, but I'll probably leave as-is for now.

Right now the ccache setting is only used for LLVM, but this tweaks it to also be used for build scripts so C++ builds like `librustc_llvm` can be a bit speedier.

Try to fix 48116 and 48192 The bug #48116 happens because of a misoptimization of the `import_path_to_string` function, where a `names` slice is empty but the `!names.is_empty()` branch is executed. https://github.com/rust-lang/rust/blob/4d2d3fc5dadf894a8ad709a5860a549f2c0b1032/src/librustc_resolve/resolve_imports.rs#L1015-L1042 Yesterday, @eddyb had locally reproduced the bug, and [came across the `position` function](https://mozilla.logbot.info/rust-infra/20180214#c14296834) where the `assume()` call is found to be suspicious. We have *not* concluded that this `assume()` causes #48116, but given [the reputation of `assume()`](#45501 (comment)), this seems higher relevant. Here we try to see if commenting it out can fix the errors. Later @alexcrichton has bisected and found a potential bug [in the LLVM side](#48116 (comment)). We are currently testing if reverting that LLVM commit is enough to stop the bug. If true, this PR can be reverted (keep the `assume()`) and we could backport the LLVM patch instead. (This PR also includes an earlier commit from #48127 for help debugging ICE happening in compile-fail/parse-fail tests.) The PR also reverts #48059, which seems to cause #48192. r? @alexcrichton cc @eddyb, @arthurprs (#47333)
