Based on the TODO, this case was added to short-circuit for ios builds,
which is no longer necessary.

The comment in this Makefile mentions rust-lang#29812 as a
dependency, but that issue has been since closed, with a statement that
the ICE of concern was resolved circa 1.12.

Here we remove this case, and just run the same branch for all targets.

Since this case statement no longer has any branches, remove it.

Didn't think it was this particular about things, but I also should
have tested locally.

It makes sense, though---`\` followed by LF would eat it, so we'd have
`sysroot done` instead of `sysroot; done` as it is parsed.  This should
pass now.

Allow to specify profiling data output directory as -Zself-profile argument.

The PR also makes `rustc` include the crate-name (if already available) in the output file name.

At some point we should add some basic tests for `-Zself-profile`.

split core::ptr module into multiple files

Cc @Centril

rename Scalar::Bits to Scalar::Raw and bits field to data

Also use this opportunity to seal some abstraction leaks (other modules constructing `Scalar::Bits` directly instead of using a constructor).

Remove special case for *ios* builds in run-make-fulldeps/print-target-list Makefile

Previous `TODO` comment in this file mentions [an issue that was closed](rust-lang#29812), and I was able to confirm locally that provided code in that issue no longer produces an ICE. Discussion on that issue seems to indicate this code was no longer needed as of 1.12.0.

I removed the `*ios*` branch from this `case` statement as it may cause confusion, then removed the case statement entirely as it only had a wildcard branch.
