Alexey Samsonov d6aa820262 [LLVMSymbolize] Factor out the logic for printing structs from DIContext. NFC.
Introduce DIPrinter which takes care of rendering DILineInfo and
friends. This allows LLVMSymbolizer class to return a structured data
instead of plain std::strings.

Alexey Samsonov 6881249895 [LLVMSymbolize] Move demangling away from printing routines. NFC.
Make printDILineInfo and friends responsible for just rendering the
contents of the structures, demangling should actually be performed
earlier, when we have the information about the originating
SymbolizableModule at hand.

Alexey Samsonov 46c1ce6ff5 Let the users of LLVMSymbolizer decide whether they want to symbolize inlined frames.
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.

Alexey Samsonov 8df3a07aa8 [LLVMSymbolize] Move ModuleInfo into a separate class (SymbolizableModule).
Summary:
This is mostly NFC. It is a first step in cleaning up LLVMSymbolize
library. It removes "ModuleInfo" class which bundles together ObjectFile
and its debug info context in favor of:
  * abstract SymbolizableModule in public headers;
  * SymbolizableObjectFile subclass in implementation.

Additionally, SymbolizableObjectFile is now created via factory, so we
can properly detect object parsing error at this stage instead of keeping
the broken half-parsed object. As a next step, we would be able to
propagate the error all the way back to the library user.

Further improvements might include:
  * factoring out the logic of finding appropriate file with debug info
    for a given object file, and caching all parsed object files into a
    separate class [A].
  * factoring out DILineInfo rendering [B].
This would make what is now a heavyweight "LLVMSymbolizer" a relatively
straightforward class, that calls into [A] to turn filepath into a
SymbolizableModule, delegates actual symbolization to concrete SymbolizableModule
implementation, and lets [C] render the result.

Alexey Samsonov 0fb6451ade [LLVMSymbolize] Don't use LLVMSymbolizer::Options in ModuleInfo. NFC.
LLVMSymbolizer::Options is mostly used in LLVMSymbolizer class anyway.
Let's keep their usage restricted to that class, especially given that
it's worth to move ModuleInfo to a different header, independent from
the symbolizer class.

Alexey Samsonov f3ecfd3af4 [LLVMSymbolize] Use symbol table only if function linkage name was requested.
Now it's enough to just specify -functions=short without additionally
providing -use-symbol-table=false.
