core/tests/num: Simplify `test_int_from_str_overflow()` test code

2018-11-14T14:01:27+00:00

This commit changes the test code to compare against easier-to-read, static values instead of relying on the result of `wrapping_add()` which may or may not result in the value that we expect.

Implement always-fallible TryFrom for usize/isize conversions that are infallible on some platforms This reverts commit 837d6c70233715a0ae8e15c703d40e3046a2f36a "Remove TryFrom impls that might become conditionally-infallible with a portability lint". This fixes #49415 by adding (restoring) missing `TryFrom` impls for integer conversions to or from `usize` or `isize`, by making them always fallible at the type system level (that is, with `Error=TryFromIntError`) even though they happen to be infallible on some platforms (for some values of `size_of::()`). They had been removed to allow the possibility to conditionally having some of them be infallible `From` impls instead, depending on the platforms, and have the [portability lint](https://github.com/rust-lang/rfcs/pull/1868) warn when they are used in code that is not already opting into non-portability. For example `#[allow(some_lint)] usize::from(x: u64)` would be valid on code that only targets 64-bit platforms. This PR gives up on this possiblity for two reasons: * Based on discussion with @aturon, it seems that the portability lint is not happening any time soon. It’s better to have the conversions be available *at all* than keep blocking them for so long. Portability-lint-gated platform-specific APIs can always be added separately later. * For code that is fine with fallibility, the alternative would force it to opt into "non-portability" even though there would be no real portability issue.

Add unit tests for `.mod_euc()` and `.div_euc()`
