As it says in the subject, should have gone long enough now that this
should be safe. This will greatly simplify dealing with LLVM for people
that just want to use the C API on windows. This is a follow up from
D35077.

The Android sanitizer tests are currently some of the most difficult
to run correctly, requiring at least 3 build directories which have
to be configured in just the right way and built in the correct order
(see e.g. [1] and the functions that it calls).
This patch adds a check-hwasan target which greatly simplifies running
the hwasan tests for gn users, taking advantage of its support for
multiple toolchains. With this the tests can be run simply by setting
an NDK path and running "ninja check-hwasan" with a compatible Android
device connected. The Linux/x86_64 and Android/aarch64 targets are
tested in parallel.

The path to the resource directory will end up being used in several
more places once the support for running check-hwasan lands. This
moves the definition to a central location so that it can be used
from those places.

This makes e.g. ToolChain::isCrossCompiling() in
clang/lib/Driver/ToolChain.cpp return the correct result
if the compiler was cross-compiled. This change also affects
llvm_default_target_triple, so cross-compiled compilers default to
targeting the cross-compilation target, which makes more sense than
the host that the compiler was compiled on.
This change will also be necessary in order for the correct triples
to appear in generated lit files for non-native targets.

Add an asm tool (will be required for building sanitizer_common on

Some of the sanitizer runtime code needs to be built with RTTI;
this allows that code to opt in to RTTI.

This is needed because otherwise if source dir is at location whose path
contains non-ASCII character then python will complain about
SyntaxError.

Since people weren't enthused about moving the .gn file to the toplevel in
D56419, here's a script to make gn at least somewhat more pleasant to invoke
(useful for gn clean, gn args --list, gn desc, etc).

Summary:
While the backend code of FileCheck relies on definition of variable
from the command-line to have an equal sign '=' and a variable name
before that, the frontend does not actually enforce it. This leads to
FileCheck crashing when invoked with invalid syntax for the -D option.
This patch adds the missing validation in the frontend. It also makes
the -D option an AlwaysPrefix option to be able to detect -D=FOO as
being a define without variable and -D as missing its value.

This shortcut mechanism for creating types was added 10 years ago, but
has seen almost no uptake since then, neither internally nor in
external projects.
The very small number of characters saved by using it does not seem
worth the mental overhead of an additional type-creation API, so,
delete it.

I didn't break all that much during upstreaming, just needs two small fixes:
- fix spelling of MCJITTests.def file
- make libLTO a shared_library to put it in bin/ on Windows where it is in the

Also change the toolchain description to use current_os instead of
host_os so that the template can be used for cross builds, and add
a current_os to the win toolchain to match the unix toolchain.

The PowerPC target itself is similar to the X86 target in https://reviews.llvm.org/rL348903
The llvm-exegesis unittests bits are similar to the corresponding AArch64 in https://reviews.llvm.org/rL350499
The whole patch is very similar to the WebAssembly target being added in https://reviews.llvm.org/rL350628
Also add a dep from tools/llvm-exegesis/lib to the AArch64 subdir, which I
failed to do in r350499.
The motivation for this target is solely that it has a unit test and I want to
enable the GN<->CMake unittest syncing check for llvm.
