Accept absolute paths in the -fuse-ld option. This patch extends the -fuse-ld option to accept a full path to an executable and use it verbatim to invoke the linker. There are generally two reasons to desire this. The first reason relates to the sad truth is that Clang is retargetable, Binutils are not. While any Clang from a binary distribution is sufficient to compile code for a wide range of architectures and prefixed BFD linkers (e.g. installed as /usr/bin/arm-none-linux-gnueabi-ld) as well as cross-compiled libc's (for non-bare-metal targets) are widely available, including on all Debian derivatives, it is impossible to use them together because the -fuse-ld= option allows to specify neither a linker prefix nor a full path to one. The second reason is linker development, both when porting existing linkers to new architectures and when working on a new linker such as LLD.

Implement the -fuse-ld= option. This commit implements the -fuse-ld= option, so that the user can specify -fuse-ld=bfd to use ld.bfd. This commit re-applies r194328 with some test case changes. It seems that r194328 was breaking macosx or mingw build because clang can't find ld.bfd or ld.gold in the given sysroot. We should use -B to specify the executable search path instead.

Vary Windows toolchain selection by -fuse-ld Summary: This change allows binutils to be used for linking with MSVC. Currently, when using an MSVC target and `-fuse-ld=bfd`, the driver produces an invalid linker invocation.
