All of these families were claiming to be a73 based, which was causing -mcpu/mtune=native to never use the newer features available to these cores. Goes through each and bumps the individual cores to their respective Big counterparts. Since this code path doesn't support big.little detection, there was already a precedent set with the Qualcomm line to choose the big cores only. Adds a comment on each line for the product's name that the part number refers to. Confirmed on-device and through Linux header naming convections. Additionally newer SoCs mix CPU implementer parts from multiple implementers. Both 0x41 (ARM) and 0x51 (Qualcomm) in the Snapdragon case This was causing a desync in information where the scan at the start to find the implementer would mismatch the part scan later on. Now scan for both implementer and part at the start so these stay in sync. Differential Revision: https://reviews.llvm.org/D94954
