Simon Atanasyan e60eae4256 [driver][mips] Adjust target triple's environment accordingly to provided ABI name
For MIPS we need to adjust not only architecture name accordingly to ABI
provided by the `-mabi` command line option, but also modify triple's
environment. For example, for `mips-linux-gnu` triple and `-mabi=n32`
option a correct final triple is `mips64-linux-gnuabin32`.

Jonas Hahnfeld fb8ca8a1ec Fix greedy FileCheck expression in test/Driver/mips-abi.c
'ld{{.*}}"' seems to match the complete line for me which is failing
the test. Only allow an optional '.exe' for Windows systems as most
other tests do.
Another possibility would be to collapse the greedy expression with
the next check to avoid matching the full line.

Simon Atanasyan 0c0fb4b765 [driver][mips] Adjust target triple accordingly to provided ABI name
Explicitly selected MIPS ABI using the `-mabi` option implies
corresponding target triple. For 'O32' ABI it's a 32-bit target triple
like `mips-linux-gnu`. For 'N32' and 'N64' ABIs it's a 64-bit target
triple like `mips64-linux-gnu`. This patch adjusts target triple
accordingly these rules like we do for pseudo-target flags '-m64',
'-m32' etc already.

Daniel Sanders 32b2d6b160 [mips] Defer validity check for CPU/ABI pairs and improve error message for invalid cases.
Summary:
The validity of ABI/CPU pairs is no longer checked on the fly but is
instead checked after initialization. As a result, invalid CPU/ABI pairs
can be reported as being known but invalid instead of being unknown. For
example, we now emit:
  error: ABI 'n32' is not supported on CPU 'mips32r2'
instead of:
  error: unknown target ABI 'n64'

Daniel Sanders 0ca86fe84d [mips] The default ABI depends on the CPU not the Arch on MTI and IMG vendor triples.
Summary:
32-bit CPU's default to O32. 64-bit CPU's default to N64. The default CPU
(mips32r2/mips64r2) still depends on the arch so there's no functional
change when the CPU isn't specified but commands like:
  clang -target mips-mti-linux-gnu -mips64r2
will now default to a 64-bit ABI like our gcc toolchains do* instead of
asserting in the backend**.

Other vendors (including Triple::UnknownVendor) still derive the default
ABI from the arch.

* Although not the same one as our gcc toolchains, clang has historically
  defaulted to N64 where gcc defaults to N32.
** Mixing O32 and a 64-bit CPU causing assertions is a long-standing bug.

Daniel Sanders 07c8654284 [mips] Kill 'support' for untested EABI.
Summary:
There are no llvm backend tests* for EABI and no EABI buildbots. There were only
three clang tests, all of which checked that -mabi=eabi was passed to the
assembler.

*There is a single backend test that specifies EABI but it actually tests MIPS16.

Simon Atanasyan a42a84e44c [Driver][Mips] If ABI name is not provided deduce it from the target triple
