Since 1, compiler-builtins makes a certain set of math symbols
weakly available on all platforms. This means we can begin exposing some
of the related functions in core, so begin this process here.

It is not possible to provide inherent methods in both core and std
while giving them different stability gates, so standalone functions are
added instead. This provides a way to experiment with the functionality
while unstable; once it is time to stabilize, they can be converted to
inherent.

For f16 and f128, everything is unstable so we can move the inherent
methods.

The following are included to start:

  • floor
  • ceil
  • round
  • round_ties_even
  • trunc
  • fract
  • mul_add
  • div_euclid
  • rem_euclid
  • powi
  • sqrt
  • abs_sub
  • cbrt

These mirror the set of functions that we have in compiler-builtins
since 1, with the exception of powi that has been there longer.

Initial implementation of `core_float_math`

Since [1], `compiler-builtins` makes a certain set of math symbols
weakly available on all platforms. This means we can begin exposing some
of the related functions in `core`, so begin this process here.

It is not possible to provide inherent methods in both `core` and `std`
while giving them different stability gates, so standalone functions are
added instead. This provides a way to experiment with the functionality
while unstable; once it is time to stabilize, they can be converted to
inherent.

For `f16` and `f128`, everything is unstable so we can move the inherent
methods.

The following are included to start:

* floor
* ceil
* round
* round_ties_even
* trunc
* fract
* mul_add
* div_euclid
* rem_euclid
* powi
* sqrt
* abs_sub
* cbrt

These mirror the set of functions that we have in `compiler-builtins`

test-various passed, the others likely only need tweaks for f128 config.

This configuration needs to be reused for tests that aren't in `std`. To
facilitate this, move the relevant portion of `build.rs` that can be
`include!`d from other locations.
Many float-related tests in `std` only depend on `core`, so move the
tests there. This also allows us to verify functions from
`core_float_math`.

Since the majority of test files need to be moved to `coretests`, move
the files here without any cleanup; this is done in a followup commit.
This makes git history slightly cleaner, but coretests will not build
immediately after this commit.
The previous commit moved all test files from `std` to `core` so git
understands the move. Not all functionality is actually testable in
`core`, however, so perform move the relevant portions back. Changes
from inherent to module methods is also done since this is the form of
math operations in `core` (as `core_float_math`).
