Because we now set the sysroot include flags early in python configure,
we don't need to set CPP/CXXCPP. We also skip the explicit compiler test
because more complete tests follow anyways.

We're always setting -dead_strip on mac builds, per
cross-mozconfig.common, we might as well not do that and revert bug
638149, which disabled adding -dead_strip with LTO: that is apparently
not a problem anymore.

vpx_mem_set_functions support is only enabled when
MOZ_VPX_NO_MEM_REPORTING is not set. It is currently set unconditionally
when building with the in-tree libvpx. When building with system libvpx,
it is set when the vpx_mem_set_functions can't be found in the system
libvpx library.
Upstream removed the vpx_mem_set_functions function in version 1.5, and
we require at least that version, meaning, in practice,
MOZ_VPX_NO_MEM_REPORTING is now always set.
We might as well remove the define and the code that's conditional to
not being defined.

It's enabled by default as of clang 7 with -Oz on aarch64 (that is,
afaict, the only platform where it's enabled), and regresses our
performance on speedometer.

The desired outcome of this change is that we'll set
-Wl,--version-script based on linker kind and not on the output of
$LINKER -v.
This is a cheap way to address a simple problem that has a complicated
ideal solution. The underlying issue is that in some situations, when
targeting Android, a macOS system ld is interrogated to determine if
a cross-compiling linker "is GNU ld" and a particular linker feature
is set in that situation. The macOS system ld doesn't pass the "is
GNU ld" test, and the linker feature isn't set; that causes link
failures, even though the actual linker has nothing to do with the
system ld.
The ideal solution is to test for linker capabilities dynamically. We
do a lot of that in old-configure.in, and we don't do any of that in
toolchain.configure. Rather than start testing in
toolchain.configure, we hard-code: a cheap solution to the immediate
problem.
MinGW suffers somewhat from the opposite problem: the linker "is GNU
ld" (compatible), but the linker checks don't happen at all. We hard-code
for MinGW based on the C compiler instead.

The GNU_AS check in old-configure depended on running with the value
of $AS before it gets reset to just be the C compiler, which breaks when
we move setting AS into moz.configure.
This patch moves the GNU_AS check to toolchain.configure and changes it
so that it works when the assembler is the C compiler. We do have to
fix things slightly for clang, because the previous check was
succeeding, but not because of clang: it was detecting the presence of
"GNU" in the output for GNU ld/gold and a message about the GNU GPL.
This is a straightforward port of MIDL_FLAGS from old-configure to
moz.configure. The only behavioral change is that it removes support for
prepending MIDL_FLAGS from the environment in configure, but I doubt anyone
uses that.
This is a fairly straightforward port of the AS tool checks from old-configure
to toolchain.configure. AS is a little quirky in that we currently do a
normal-looking check for it, but then override that value to be the C compiler
for non-Windows builds, and ml[64]/armasm64 for Windows builds.
After migrating those checks, the only things left in the MOZ_DEFAULT_COMPILER
macro in compiler-opts.m4 were some unused bits, so I removed them:
* Setting of CPP/CXXCPP, which are set in toolchain.configure now
* Setting HOST_LDFLAGS to empty, which doesn't seem particularly useful.
There was also a quirky old test that the assembler was ml[64] when js-ctypes
is enabled that I removed, I don't think it provides any value since this
patch will ensure that we're using the right assembler for Windows builds.
Some build flags are being passed by the build system: they're passed in a text
file called extra-bindgen-flags.in that's filled at configure time.
Other flags have to be inferred from the current target/host combination, in
Cranelift's build script directly. This is mostly cargo-culted from the
ServoBindings.toml file, and should probably be merged in the build system at
some point.
Some Windows-specific adjustments were needed to provide access to libclang for
bindgen support, by adding clang-cl to the plain Spidermonkey Windows builds.

It's nicer to have all that logic in one place, and to be able to common
up the Unix-y flags setting. The Makefile constructs in string values
is gross, but it's no worse than we had before.
