Simon Atanasyan db81c7b9c9 [mips] Fix handling of GNUABIN32 environment in a target triple
The `GNUABIN32` environment in a target triple implies using the N32
ABI. This patch adds support for this environment and switches on N32
ABI if necessary.

Mehdi Amini 557c20a886 Remove compile time PreserveName in favor of a runtime cc1 -discard-value-names option
Summary:
This flag is enabled by default in the driver when NDEBUG is set. It
is forwarded on the LLVMContext to discard all value names (but
GlobalValue) for performance purpose.

This an improved version of D18024

Daniel Sanders ed39f58390 [mips] Zero-sized structs cannot be ignored in MipsABIInfo::classifyReturnType() for O32
Summary:
They are returned indirectly which causes the other arguments to move to
the next argument slot.

With this, utils/ABITest does not discover any failing cases in the first
500 attempts on big/little endian for O32. Previously some of these failed.
Also tested N32/N64 little endian (big endian has other known issues) with
no issues.
