Summary:
This is a pure refactoring change. It just moves code that is
related to filesystem operations from sanitizer_common.{cc,h} to
sanitizer_file.{cc,h}. This makes it cleaner to disable the
filesystem-related code for a new port that doesn't want it.
Submitted on behalf of Roland McGrath.

This patch starts passing architecture information about a module to llvm-symbolizer and into text reports. This fixes the longstanding x86_64/x86_64h mismatch issue on Darwin.

Add support for Swift names when symbolicating sanitizer traces. This is
now relevant since TSan and ASan support have been added to Swift on OS X.

Patch by Maxim Ostapenko!
Summary:
Right now, Addr2Line symbolizer in asan_symbolize.py doesn't support inline functions symbolization. This might be a useful feature for using ASan on embedded systems.
Test results:
$ cat test.c
static inline void FooBarBaz() {
__sanitizer_print_stack_trace();
}
int main() {
FooBarBaz();
return 0;
}
$ clang test.c -fsanitize=address -g -O2 -o test.x && ./test.x &> /tmp/test.log
$ ./projects/compiler-rt/lib/asan/scripts/asan_symbolize.py -l /tmp/test.log

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.

This fixes a minor error checking bug around calling
internal_read/write, and makes the code more portable for D11791.

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.
