Summary:
llvm-symbolizer understands both PDBs and DWARF, so it's a better bet if
it's available. It prints out the function parameter types and column
numbers, so I needed to churn the expected test output a bit.
This makes most of the llvm-symbolizer subprocessing code
target-independent. Pipes on all platforms use fd_t, and we can use the
portable ReadFromFile / WriteToFile wrappers in symbolizer_sanitizer.cc.
Only the pipe creation and process spawning is Windows-specific.
Please check that the libcdep layering is still correct. I don't know
how to reproduce the build configuration that relies on that.

On OS X, dladdr() provides mangled names only, so we need need to demangle in
DlAddrSymbolizer::SymbolizePC.

They are currently still *not* used, "llvm-symbolizer" is still the default symbolizer on OS X.
