MIR: hide .rodata constants vs by-ref ABI clash in trans.

Back in #45380, constants were copied into locals during MIR creation to ensure that arguments ' memory can be used by the callee, if the constant is placed in `.rodata` and the ABI passes it by-ref.

However, there are several drawbacks (see https://github.com/rust-lang/rust/pull/45380#discussion_r150447709), most importantly the complication of constant propagation (UB if a constant ends up in `Call` arguments) and inconveniencing analyses.

Instead, I've modified the `rustc_trans` implementation of calls to copy an `Operand::Constant` argument locally if it's not immediate, and added a test that segfaults without the copy.

incr.comp.: Implement query result cache and use it to cache type checking tables.

This is a spike implementation of caching more than LLVM IR and object files when doing incremental compilation. At the moment, only the `typeck_tables_of` query is cached but MIR and borrow-check will follow shortly. The feature is activated by running with `-Zincremental-queries` in addition to `-Zincremental`, it is not yet active by default.
