Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.

[MSP430] Generate EABI-compliant libcalls Updates the MSP430 target to generate EABI-compatible libcall names. As a byproduct, adjusts the hardware multiplier options available in the MSP430 target, adds support for promotion of the ISD::MUL operation for 8-bit integers, and correctly marks R11 as used by call instructions. Patch by Andrew Wygle. Differential Revision: https://reviews.llvm.org/D32676 llvm-svn: 302820
