39a58c38a0 introduce the rather simpler symbol-cache in place of symbol-map 
The symbol map is not good for incremental: it has inputs from every fn
in existence, and it will change if anything changes. One could imagine
cheating with the symbol-map and exempting it from the usual dependency
tracking, since the results are fully deterministic. Instead, I opted to
just add a per-CGU cache, on the premise that recomputing some symbol
names is not going to be so very expensive.

f2c7917402 translate drop glue using MIR 
Drop of arrays is now translated in trans::block in an ugly way that I
should clean up in a later PR, and does not handle panics in the middle
of an array drop, but this commit & PR are growing too big.

aac5ba5dab resolve instances to ty::Instance directly 
This removes the duplication between collector, callee, and (eventually)
MIRI.

1a7aa75332 Rollup merge of #36960 - michaelwoerister:linker-regression, r=eddyb 
Linker regression

This should fix the symbol conflicts reported in #36852.
The PR also makes some debug output a bit more informative.

10c3134da0 std: Stabilize and deprecate APIs for 1.13 
This commit is intended to be backported to the 1.13 branch, and works with the
following APIs:

Stabilized

* `i32::checked_abs`
* `i32::wrapping_abs`
* `i32::overflowing_abs`
* `RefCell::try_borrow`
* `RefCell::try_borrow_mut`
* `DefaultHasher`
* `DefaultHasher::new`
* `DefaultHasher::default`

Deprecated

* `BinaryHeap::push_pop`
* `BinaryHeap::replace`
* `SipHash13`
* `SipHash24`
* `SipHasher` - use `DefaultHasher` instead in the `std::collections::hash_map`
  module

Closes #28147
Closes #34767
Closes #35057
Closes #35070

2f9fff2191 Keep multiple files per work-product 
In the older version, a `.o` and ` .bc` file were separate
work-products.  This newer version keeps, for each codegen-unit, a set
of files of different kinds. We assume that if any kinds are available
then all the kinds we need are available, since the precise set of
switches will depend on attributes and command-line switches.

Should probably test this: the effect of changing attributes in
particular might not be successfully tracked?

58d4b8edd3 Modify trans to skip generating .o files 
This checks the `previous_work_products` data from the dep-graph and
tries to simply copy a `.o` file if possible.  We also add new
work-products into the dep-graph, and create edges to/from the dep-node
for a work-product.
