Assembly-related configuration was added in 1621c6dbf9eb ("Use
`specialized-div-rem` 1.0.0 for division algorithms") to account for
Cranelift not yet supporting assembly. This hasn't been relevant for a
while, so we no longer need to gate `asm!` behind this configuration.
Thus, remove `cfg(not(feature = "no-asm"))` in places where there is no
generic fallback.
There are other cases, however, where setting the `no-asm` configuration
enables testing of generic version of builtins when there are platform-
specific implementations available; these cases are left unchanged. This
could be improved in the future by exposing both versions for testing
rather than using a configuration and running the entire testsuite
twice.
This is the compiler-builtins portion of
https://github.com/rust-lang/rust/pull/144471.

# The manifest at `../compiler-builtins` is what actually gets used in the
|
|
# rust-lang/rust tree; however, we can't build it out of tree because it
|
|
# depends on `core` by path, and even optional Cargo dependencies need to be
|
|
# available at build time. So, we work around this by having this "shim"
|
|
# manifest that is identical except for the `core` dependency and forwards
|
|
# to the same sources, which acts as the `compiler-builtins` Cargo entrypoint
|
|
# for out of tree testing
