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] Mark aggregate arguments passed in registers with the inreg attribute Summary: This allows us to easily identify them in the backend which in turn allows us to handle them correctly for big-endian targets (where they must be shifted into the upper bits of the register).
