Adds a check to avoid symbolization when printing stack traces if the
stack_trace_format flag does not need it. While there is a symbolize
flag that can be turned off to skip some of the symbolization,
SymbolizePC() still unconditionally looks up the module name and offset.
Avoid invoking SymbolizePC() at all if not needed.
This is an efficiency improvement when dumping all stack traces as part
of the memory profiler in D87120, for large stripped apps where we want
to symbolize as a post pass.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

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.

Summary:
With this patch, we have a flag to toggle displaying source locations in
the regular style:
file:line:column
or Visual Studio style:
file(line,column)
This way, they get picked up on the Visual Studio output window and one
can double-click them to get to that file location.

Summary:
This commit introduces function __sanitizer::RenderFrame()
that allows to render the contents of AddressInfo (essentially, symbolized stack frame)
using the custom format string. This function can be used to
implement stack frame formatting for both ThreadSanitizer and
generic StackTrace::Print(), used in another places. This paves the
way towards allowing user to control the format of stack frames,
obtaining them in any format he desires, and/or enforcing the consistent
output from all sanitizers.
