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.

[mips] Fix handling of GNUABIN32 environment in a target triple The `GNUABIN32` environment in a target triple implies using the N32 ABI.

[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.
