As it turns out, the version the minidump-stackwalk tasks use (1.31), is
the first version that actually builds the project: 1.30 and earlier
fail because for some reason, cargo wants to read all Cargo.toml files
in the workspace, including unrelated ones, and barfs on features that
weren't supported until 1.31.

When building Gecko/Android/aarch64 on Windows, `--target` parameter may not be incorrect value. Although `check_compiler`'s `info` is target compiler, clang on Windows is always detected as `clang-cl`, not `clang`.
```
c:/Users/mkato/.mozbuild/clang/bin/clang.exe -E -dM - < /dev/null
...
#define _MSC_VER 1916
```
So even if using clang on Windows, not clang-cl, we should detect as 'clang' correctly

When host and target are different compiler type, triple for rustc may be incorrect. If target is clang, host is always clang, not using host compiler type.
Example, when host is clang-cl for windows, and target is clang for Android, host's triple for ructc sets `windows-gnu`, not `windows-msvc`.

The SDK headers may not be installed in /usr/include. The usual response
has been to have people run e.g. `open
/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg`
which is not really sustainable.
This makes builds that happen on a macOS host try to detect their SDK
and use that as a default for --with-macos-sdk, which has the side
effect of enabling the SDK version check in that configuration.

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.

We've been relying on frame pointers being indirectly enabled via things
like --enable-profiling for some time, but this doesn't scale because
some things may want frame pointers while wanting --disable-profiling.
So we move MOZ_FRAMEPTR_FLAGS to python configure and add a new option
to decide whether to enable frame pointers or not.

Bug 1394825 bumped the minimum version of clang we use on automation,
for the base toolchain jobs, and there's a libclang test for bindgen,
but we should reject the compiler in the first place.
The check to do that works in both C and C++, contrary to the original
3.6 test that was checking a C++ feature ; the test was later changed
for 3.9, using a check that would have worked in both C and C++, but
the C exception was left around. We remove it now.

The current logic is that if the compiler somehow uses gold rather than
BFD ld by default, we let it, but if it uses BFD ld, we default to lld.
When doing Android builds, the compiler finds the linker in the NDK, and
the default `ld` binary is gold. So we currently end up using fold for
Android builds.
Here, we change the logic such that we use lld when the default linker
the compiler uses is either BFD ld or gold. We can't go with "is not
lld" because the other possible kind, ld64, is what we actually want to
use on mac, since lld doesn't support mach-o fully just yet.

The current setup for bindgen relies on either finding clang/libclang
from the output of llvm-config, or from the paths given via the
configure flags --with-clang-path/--with-libclang-path.
One _very_ common problem is that the llvm-config we end up using does
not correspond to the clang used for compilation, which has some
undesirable side effect, like failing to build.
So instead of relying on llvm-config, we do the following:
- when the compiler is clang, we just use that
- when the compiler is clang-cl, we use clang from the same directory
- otherwise, we either try to find clang in PATH, or rely on
--with-clang-path.
Once clang is found, we try to deduce the location of the corresponding
libclang via the output of `clang -print-search-dirs`, or rely on
--with-libclang-path.
