This patch adds an `is_optimized` variable, orthogonal to `is_debug`, to allow for a gn analogue to `RelWithDebInfo` builds.
As part of this we'll want to explicitly enable GC+ICF, for the sake of `is_debug && is_optimized` builds. The flags normally default to true except that if you pass `/DEBUG` they default to false.

Mostly achieved by assuming that anything that isn't Win or Mac is ELF,
which seems reasonable enough for now.

As far as I can tell, malloc.h is only being used here to provide
a definition of mallinfo (malloc itself is declared in stdlib.h via
cstdlib). We already have a macro for whether mallinfo is available,
so switch to using that instead.

Not depending on //clang/lib/StaticAnalyzer/Core and
//clang/lib/StaticAnalyzer/Frontend causes a linker error even if
ClangSACheckers are not supported.
Undefined symbols for architecture x86_64:

Trivial fix: decode was not called for all subprocess.check_output calls.

NDK r19 includes a sysroot that can be used directly by the compiler
without creating a standalone toolchain, so we just need a handful
of flags to point Clang there.

The current build was producing names like llvm-undname.exe.pdb, which looks unusual to me at least. This switches them to the more common llvm-undname.pdb style.

Without /DEBUG, the /Zi doesn't on its own create PDB files.
And since ninja runs multiple compilations in parallel, we need /FS to prevent contention on PDBs.

We'll need to do this eventually if we create an installable package.
For now, this lets me use the archives to build Android, whose build
system wants to copy the archives to another location.

check-llvm already listed llvm-lit as script which counts as a dep, so running
check-llvm worked fine, but `ninja -C out/gn llvm/test` didn't build llvm-lit
before if it wasn't already there.

Fixes a minor regression from r351248.
While here, also make it possible to opt out of lld by saying
use_lld=false when clang_base_path is set. (use_lld still defaults to
true if clang_base_path is set.)

- gcc doesn't understand -Wstring-conversion, so pass that only to clang
- disable a few gcc warnings that are noisy and also disabled in the cmake build
- -Wstrict-aliasing pointed out that the cmake build builds clang with
-fno-strict-aliasing, so do that too

This is a remnant from before the gn build had a working config.h.
Defining LLVM_LIBXML2_ENABLED only for targets that depend on build/libs/xml is
nice in that only some of the codebase needs to be rebuilt when
llvm_enable_libxml2 changes -- but config.h already defines it and defining it
there and then redundantly a second time for some targets is worse than having
it just in config.h.
No behavior change.

r291284 added a nice mechanism to consistently pass CMake on/off toggles to
lit. This change uses it for LLVM_LIBXML2_ENABLED too (which was added around
the same time and doesn't use the new system yet).
Also alphabetically sort the list passed to llvm_canonicalize_cmake_booleans()
in llvm/test/CMakeLists.txt.
No intended behavior change.

The check-hwasan build files assert that current_os == "linux" || current_os ==
"android", so pull it in only there.
ar is unused on mac, so don't set it in the stage2 toolchain. (It'd be nicer to
use llvm-libtool on mac instead of host libtool, but llvm-libtool doesn't seem
to understand the -no_warning_for_no_symbols flag.)

llvm/tools sets LLVM_TOOL_LTO_BUILD to Off if LLVM_ENABLE_PIC=OFF, but that's
not visible in llvm/test.
r289662 added the llvm_tool_lto_build lit parameter, there the intent was to
use it with an explicit -DLLVM_TOOL_LTO_BUILD=OFF, which is visible globally.
On the review for that (D27739), a mild preference was expressed for using a
lit parameter over checking the existence of libLTO.dylib. Since that works
with the LLVM_ENABLE_PIC=OFF case too and since it matches what we do for the
gold plugin, switch to that approach.
