Anna Zaks 60469e2ac0 [sanitizers] Teach the internal demangler about Swift names 
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.

Alexey Samsonov 1b76da6a6c Support inline functions symbolization in Addr2Line symbolizer. 
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
    #0 0x42095e in __sanitizer_print_stack_trace _asan_rtl_

Reid Kleckner 7d9e1e1259 [Windows] Use llvm-symbolizer before using dbghelp 
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.

Reid Kleckner a0f78fef74 [sanitizers] Use portable file read/write wrappers on process pipes 
This fixes a minor error checking bug around calling
internal_read/write, and makes the code more portable for D11791.

Kuba Brecka eefb2e2703 Demangling for DlAddrSymbolizer 
On OS X, dladdr() provides mangled names only, so we need need to demangle in
DlAddrSymbolizer::SymbolizePC.

Kuba Brecka 656e184f6c Adding the implementation of atos and dladdr symbolizers for OS X. 
They are currently still *not* used, "llvm-symbolizer" is still the default symbolizer on OS X.
