[PATCH] D21465: [llc+llvm-mc] Replace the hidden -target-abi option with a -mabi thats visible in --help.

Although this patch is a cosmetic change, it is important for MIPS since it
is a prerequisite of moving the ABI to the environment component of the
triple (much like X86's and ARM's GNUX32, GNUEABI, and GNUEABIHF) which in
turn is important for both enabling IAS by default for the N64 ABI and for
distinguishing between the N32 and N64 in order to fix IAS for N32 and
prevent inappropriate interlinking in the IRLinker. Follow-up patches will try
to modify the triple according to -mabi for targets that prefer this instead of
passing it to MCTargetOptions::ABIName.

See http://reviews.llvm.org/D20916 (which this patch has been extracted
from) for more detail on the wider context of this patch as well as an
explanation as to why having the ABI name in MCTargetOptions does not work
for Mips.

The test changes are all switching -target-abi to -mabi.

A similar patch will be posted for 'clang -cc1' and 'clang -cc1as' (the
latter currently accepts a -target-abi option but ignores it, I'll fix this
at the same time).
