Rui Ueyama 3f851704c1 Move new lld's code to Common subdirectory.
New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

Zachary Turner 264b5d9e88 Move Object format code to lib/BinaryFormat.
This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.

Rui Ueyama a453c0a5ad Merge DarwinLdDriver and Driver.
Now that DarwinLdDriver is the only derived class of Driver.
This patch merges them and actually removed the class because
they can now just be non-member functions. This change simplifies
a common header, Driver.h.

Rui Ueyama 3b9388f456 Remove DriverTest.h.
Because the class is used only by one instance, we do not have to
use template there in DriverTest.h. Everything can be moved to
DarwinLdDriverTest.cpp.

Rui Ueyama e7b330052f Move functionality of UniversalDriver to the entry point file.
UniversalDriver was used as a dispatcher to each platform-specific driver.
It had its own Options.td file. It was not just too much to parse only a
few options (we only want to parse -core, -flavor or argv[0]),
but also interpreted arguments too early. For example, if you invoke lld as
"lld -flavor gnu ... -help", then you'd get the UniversalDriver's help
message instead of GnuDriver's. This patch eliminates the use of Options
from the dispatcher.

Pete Cooper 351164504a Add support for export_dynamic cmdline option and behaviour.
This option matches the behaviour of ld64, that is it prevents globals
from being dead stripped in executables and dylibs.

Pete Cooper 6e319c7b42 Fix DarwinLdDriverTest.cpp to pass real llvm options.
After r255819, parse() actually parses what you pass it.

This test was failing because it passed '--debug-only' which isn't in
release builds, but also 'foo' which isn't an option at all.

We now pass -enable-tbaa and -enable-misched which are real options.

Nick Kledzik 635f9c7158 [mach-o] Let darwin driver infer arch from .o files if -arch not used.
Mach-O has a "fat" (or "universal") variant where the same contents built for
different architectures are concatenated into one file with a table-of-contents
header at the start.  But this leaves a dilemma for the linker - which
architecture to use.

Normally, the linker command line -arch is used to force which slice of any fat
files are used.  The clang compiler always passes -arch to the linker when
invoking it.  But some Makefiles invoke the linker directly and don’t specify
the -arch option.  For those cases, the linker scans all input files in command
line order and finds the first non-fat object file.  Whatever architecture it
is becomes the architecture for the link.

Rui Ueyama 8db1eddc07 Make Driver::link and LinkingContext::validate return true on success.
This patch inverts the return value of these functions, so that they return
"true" on success and "false" on failure. The meaning of boolean return value
was mixed in LLD; for example, InputGraph::validate() returns true on success.
With this patch they'll become consistent.
