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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@302820 91177308-0d34-0410-b5e6-96231b3b80d8
