5b6a464358 io: Use Vec::resize in Cursor<Vec<u8>> for more efficient zero fill
Vec::resize compiles to better code than .extend(repeat(0).take(n)) does
right now.

9f26f14dc9 Auto merge of #26869 - alexcrichton:fix-msvc-sepcomp, r=nrc
This commit alters the implementation of multiple codegen units slightly to be
compatible with the MSVC linker. Currently the implementation will take the N
object files created by each codegen unit and will run `ld -r` to create a new
object file which is then passed along. The MSVC linker, however, is not able to
do this operation.

The compiler will now no longer attempt to assemble object files together but
will instead just pass through all the object files as usual. This implies that
rlibs may not contain more than one object file (if the library is compiled with
more than one codegen unit) and the output of `-C save-temps` will have changed
slightly as object files with the extension `0.o` will not be renamed to `o`
unless requested otherwise.

9bc8e6d147 trans: Link rlibs to dylibs with --whole-archive
This commit starts passing the `--whole-archive` flag (`-force_load` on OSX) to
the linker when linking rlibs into dylibs. The primary purpose of this commit is
to ensure that the linker doesn't strip out objects from an archive when
creating a dynamic library. Information on how this can go wrong can be found in
issues #14344 and #25185.

The unfortunate part about passing this flag to the linker is that we have to
preprocess the rlib to remove the metadata and compressed bytecode found within.
This means that creating a dylib will now take longer to link as we've got to
copy around the input rlibs to a temporary location, modify them, and then
invoke the linker. This isn't done for executables, however, so the "hello
world" compile time is not affected.

This fix was instigated because of the previous commit where rlibs may not
contain multiple object files instead of one due to codegen units being greater
than one. That change prevented the main distribution from being compiled with
more than one codegen-unit and this commit fixes that.

Closes #14344
Closes #25185

020d201a66 Auto merge of #26849 - bluss:read-to-end-memset, r=alexcrichton
Improve zerofill in Vec::resize and Read::read_to_end

We needed a more efficient way to zerofill the vector in read_to_end.
This to reduce the memory intialization overhead to a minimum.

Use the implementation of `std::vec::from_elem` (used for the vec![]
macro) for Vec::resize as well. For simple element types like u8, this
compiles to memset, so it makes Vec::resize much more efficient.

a5cc17adaa io: Simplify BufReader::with_capacity
Use the vec![] macro directly to create a sized, zeroed vector.

This should result in a big speedup when creating BufReader, because
vec![0; cap] compiles to a memset call, while the previous extend code
currently did not.

9f4d5b4be1 Improve PartialEq for slices
Exploiting the fact that getting the length of the slices is known, we
can use a counted loop instead of iterators, which means that we only
need a single counter, instead of having to increment and check one
pointer for each iterator.

50df2a09b8 Auto merge of #26863 - brson:revert-stageversion, r=alexcrichton
This reverts https://github.com/rust-lang/rust/pull/26599, which puts the stage number in the output of `--version -v`, but is not supposed to put it in the 'stage2' compiler, which is what most people refer to the binary we deploy.

The picture is not so clear though because of how stage 'promotions' happen in the build and also because the windows build deploys stage3, not stage2.
