194a91b0ce rustbuild: Fix dependency tracking with new Cargo
The recent Cargo update changed filenames, which broke a lot of incremental
rustbuild builds. What it thought were the output files were indeed no longer
the output files! (wreaking havoc).

This commit updates this to stop guessing filenames of Cargo and just manage
stamp files instead.

3fd5fdd8d3 crate-ify compiler-rt into compiler-builtins
libcompiler-rt.a is dead, long live libcompiler-builtins.rlib

This commit moves the logic that used to build libcompiler-rt.a into a
compiler-builtins crate on top of the core crate and below the std crate.
This new crate still compiles the compiler-rt instrinsics using gcc-rs
but produces an .rlib instead of a static library.

Also, with this commit rustc no longer passes -lcompiler-rt to the
linker. This effectively makes the "no-compiler-rt" field of target
specifications a no-op. Users of `no_std` will have to explicitly add
the compiler-builtins crate to their crate dependency graph *if* they
need the compiler-rt intrinsics. Users of the `std` have to do nothing
extra as the std crate depends on compiler-builtins.

Finally, this a step towards lazy compilation of std with Cargo as the
compiler-rt intrinsics can now be built by Cargo instead of having to
be supplied by the user by some other method.

0a62676c73 fix "X is not a member of trait Y" span labels
The span labels for associated types and consts were hardcoded to `Foo`
rather than substituting the name of the trait.

This also normalizes the wording for associated methods', traits', and
consts' span labels.

Fixes #36428.

00ce2c0ffa Auto merge of #36360 - orbea:docdir, r=alexcrichton
Allow setting --docdir

This will allow setting `--docdir` during configure, this is useful because not all linux distributions install documentation to `/usr/share/doc`.  For example in Slackware documentation is installed to `/usr/doc/$PRGNAM-$VERSION` and `/usr/share/doc` is a symlink to `/usr/doc`.

To use this `./configure --docdir=/usr/doc/$PRGNAM-$VERSION` can be used.

826f673664 Lazily construct panic messages in char_lit().
This reduces the time taken to run
`rustc -Zparse-only rustc-benchmarks/issue-32278-big-array-of-strings`
from 0.18s to 0.15s on my machine, and reduces the number of
instructions (as measured by Cachegrind) from 1.34B to 1.01B.

With the change applied, the time to fully compile that benchmark is
1.96s, so this is a 1.5% improvement.

4d9132357f Auto merge of #36355 - bluss:vec-extend-from-slice-aliasing-workaround, r=alexcrichton
Work around pointer aliasing issue in Vec::extend_from_slice, extend_with_element

Due to missing noalias annotations for &mut T in general (issue #31681),
in larger programs extend_from_slice and extend_with_element may both
compile very poorly. What is observed is that the .set_len() calls are
not lifted out of the loop, even for `Vec<u8>`.

Use a local length variable for the Vec length instead, and use a scope
guard to write this value back to self.len when the scope ends or on
panic. Then the alias analysis is easy.

This affects extend_from_slice, extend_with_element, the vec![x; n]
macro, Write impls for Vec<u8>, BufWriter, etc (but may / may not
have triggered since inlining can be enough for the compiler to get it right).

4812cf392f Auto merge of #36369 - uweigand:s390x, r=alexcrichton
Add s390x support

This adds support for building the Rust compiler and standard
library for s390x-linux, allowing a full cross-bootstrap sequence
to complete.  This includes:

- Makefile/configure changes to allow native s390x builds
- Full Rust compiler support for the s390x C ABI
  (only the non-vector ABI is supported at this point)
- Port of the standard library to s390x
- Update the liblibc submodule to a version including s390x support
- Testsuite fixes to allow clean "make check" on s390x

Caveats:

- Resets base cpu to "z10" to bring support in sync with the default
  behaviour of other compilers on the platforms.  (Usually, upstream
  supports all older processors; a distribution build may then chose
  to require a more recent base version.)  (Also, using zEC12 causes
  failures in the valgrind tests since valgrind doesn't fully support
  this CPU yet.)

- z13 vector ABI is not yet supported.  To ensure compatible code
  generation, the -vector feature is passed to LLVM.  Note that this
  means that even when compiling for z13, no vector instructions
  will be used.  In the future, support for the vector ABI should be
  added (this will require common code support for different ABIs
  that need different data_layout strings on the same platform).

- Two test cases are (temporarily) ignored on s390x to allow passing
  the test suite.  The underlying issues still need to be fixed:
  * debuginfo/simd.rs fails because of incorrect debug information.
    This seems to be a LLVM bug (also seen with C code).
  * run-pass/union/union-basic.rs simply seems to be incorrect for
    all big-endian platforms.

c8b656bea5 Remove unnecessary cmp::min from BufWriter::write
The first branch of the if statement already checks if `buf.len() >= self.buf.capacity()`, which makes the `cmp::min(buf.len(), self.buf.capacity())` redundant: the result will always be `buf.len()`. Therefore, we can pass the `buf` slice directly into `Write::write`.
