Bug 1546136 wrapped subprocess execution output to capture cmake's, but
at the detriment of other output, and hiding everything unless an error
occurs.
So instead, we only capture the output when the called process is cmake,
and even when it is cmake, we don't pipe stderr at all (since we only
care about cmake's stdout) and we print out stdout as it comes in rather
than later. We then later check the output for hints at the more useful
cmake logs and dump them.
While here, add verbosity to ninja output (which gives the command
lines, rather than generic "Building foo.o" output).

This change gives us the ability to selectively turn on cross-language
PGO, just like we have the ability to selectively turn on cross-language LTO.
There is room for things to go wrong here: it's not guaranteed that
`--enable-profile-generate=cross` will always be used with
`--enable-profile-use=cross`. Nothing bad will happen in the sense that
the build will succeed, but it's possible that we miss out on
optimizations on the Rust side. Either we fail to generate profile data
for the Rust code, or the Rust compiler fails to use the profile data.
In the future, we may want to default to cross-language PGO to avoid
these kind of mismatches.

To do properly checks on LLVM version correspondence between `clang` and
`rustc`, we need information about both of those compilers to be
available. The current placement of the LTO/PGO checks is after we know
something about `clang`, but before we know something about `rustc`.
Therefore we need to move those checks after we've gathered information
about `rustc`.
The PGO bits come along for this bug because the LTO bits depend on
them, and we're going to need the Rust information for cross-language
PGO checks in a different bug. So we might as well move everything all
at once.

On Windows in Python 2, the subprocess module requires the use of bytes with
the 'env' argument. For that reason, we would sometimes use byte strings with
'os.environ' like so:
os.environ[b"FOO"] = b"bar"
However, this is a failure with Python 3 as 'os.environ' must only be used with
the text type. This patch creates a new 'setenv' helper that ensures we create
new environment with 'bytes' on Python 2, and 'text' on Python 3.

This patch is in support of adding a variant of Static{Auto,Ref}Ptr for use as
static locals, taking advantage of C++11 "magic statics" such that we can lazily
initialize those variables in a thread-safe way.
In support of those classes, this patch adds two new attributes:
* `moz_static_local_class` to ensure that any instantiations of that class only
occur as static local variables;
* `moz_trivial_dtor` to ensure that these classes do not implicitly call `atexit`
and add a whole bunch of shutdown crap.
`moz_static_local_class` works similarly to `moz_global_class`, except that its
object must only instantiate as static locals.
`TrivialDtorChecker` is based on `TrivialCtorDtorChecker`, with the ctor-specific

This build re-uses the PGO profile from the win64 build in the
win64-aarch64-shippable-no-eme part of the aarch64 build. Even though
the profile isn't generated on the smae platform, we still get enough of
a performance win to make this worthwhile.
Note that the pgo_flags() in configure need to be tweaked slightly since
we don't supprt the -fprofile-generate flag for aarch64 (we don't build
the clang_rt.profile lib there). So we always want to return the flags
namespace to make sure we get the use_* versions of flags, which we do

likely event that a user happens to have one of these installed in their

find it.

With clang-cl and PGO enabled, toolchain.configure automatically turns
on LTO for compatibility with MSVC. However, MOZ_PGO is set for both the
profile-generate and profile-use builds in a 3-tier PGO setup via
imply_option(), but we only want LTO enabled for the profile-use build
(see bug 1483778).
For 1-tier PGO builds, which are still used by local developers, MOZ_PGO
will be set and --enable-profile-generate will be unset, so LTO will be
automatically enabled. The profiledbuild target in make is responsible
for disabling MOZ_LTO on the profile-generate build.
For 3-tier PGO builds, MOZ_PGO will still be set, so we can skip setting
LTO in configure when --enable-profile-generate is set.
