[Fuchsia] Build spam from LLVM Subzero build

Project Member Reported by w...@chromium.org, Jan 15

Issue description

CL https://chromium-review.googlesource.com/c/chromium/src/+/1170040 enabled SwiftShader under Fuchsia, meaning that we're actually building LLVM Subzero for that platform.  LLVM Subzero/s Process.inc abstracts mallinfo() usage and getrusage() calls, but does not have implementations for Fuchsia, nor does Fuchsia set any of the recognized HAVE_ macros.

We should provide Fuchsia-specific implementations, if possible.

and

https://cs.chromium.org/chromium/src/third_party/swiftshader/third_party/llvm-subzero/lib/Support/Unix/Process.inc?l=68

are the relevant lines.

It looks like GetMallocInfo() is only used to back getMemUsage() in lib/Support/Timer.cpp, and we can get memory usage information via zx_object_get_info(ZX_INFO_TASK_STATS) at present.

For CPU usage we can get total-runtime per-thread, but I don't believe we yet have an API to get that per-process.
