The core of the change is supposed to be NFC, however it also fixes
what I believe was an undefined behavior when calling:
va_start(ValueArgs, Desc);
with Desc being a StringRef.

looking for it along $PATH. This allows installs of LLVM tools outside of
$PATH to find the symbolizer and produce pretty backtraces if they crash.

Summary:
Previously we would try to load PDBs for every PE executable we tried to
symbolize. If that failed, we would fall back to DWARF. If there wasn't
any DWARF, we'd print mostly useless symbol information using the export
table.
With this change, we only try to load PDBs for executables that claim to
have them. If that fails, we can now print an error rather than falling
back silently. This should make it a lot easier to diagnose and fix
common symbolization issues, such as not having DIA or not having a PDB.

Introduce DIPrinter which takes care of rendering DILineInfo and
friends. This allows LLVMSymbolizer class to return a structured data
instead of plain std::strings.

Introduce LLVMSymbolizer::symbolizeInlinedCode() instead of switching
on PrintInlining option passed to the constructor. This will be needed
once we retrun structured data (instead of std::string) from
LLVMSymbolizer and move printing logic out.

Specifically, this patch correctly respects the -demangle option,
and additionally adds a hidden --relative-address option allows
input addresses to be relative to the module load address instead
of absolute addresses into the image.

llvm-symbolizer will consult one of the .dSYM paths passed via -dsym-hint
if it fails to find the .dSYM bundle at the default location.

Change --functions option in llvm-symbolizer tool to accept
values "none", "short" or "linkage". Update the tests and docs
accordingly.

Example:
>DATA bin/clang 0x26e8e40
<llvm::SparcSubTypeKV
<40799808 416
The last line is address and size of the object.

Again, tools are trickier to pick the main module header for than
library source files. I've started to follow the pattern of using
LLVMContext.h when it is included as a stub for program source files.

This is the second and last (2/2) part of a change that moves llvm-symbolizer to llvm/tools/, which will allow to build it
with both cmake and configure+make.
