Jonathan Brouwer 83e6dbf9e1 Rollup merge of #151900 - tgross35:num-internal-imp, r=Mark-Simulacrum
num: Separate public API from internal implementations

Currently we have a single `core::num` module that contains both thin wrapper API and higher-complexity numeric routines. Restructure this by moving implementation details to a new `imp` module.

This results in a more clean separation of what is actually user-facing compared to items that have a stability attribute because they are public for testing.

The first commit does the actual change then the second moves a portion back.

The files here use the LLVM FileCheck framework, documented at https://llvm.org/docs/CommandGuide/FileCheck.html.

One extension worth noting is the use of revisions as custom prefixes for FileCheck. If your codegen test has different behavior based on the chosen target or different compiler flags that you want to exercise, you can use a revisions annotation, like so:

// revisions: aaa bbb
// [bbb] compile-flags: --flags-for-bbb

After specifying those variations, you can write different expected, or explicitly unexpected output by using <prefix>-SAME: and <prefix>-NOT:, like so:

// CHECK: expected code
// aaa-SAME: emitted-only-for-aaa
// aaa-NOT:                        emitted-only-for-bbb
// bbb-NOT:  emitted-only-for-aaa
// bbb-SAME:                       emitted-only-for-bbb
