AMDGPU ISA isn't backwards compatible and hence -mcpu must always be specified during disassembly. However, the AMDGPU target CPU is stored in e_flags in the ELF object. This patch allows targets to implement CPU string detection, and also implements it for AMDGPU by looking at e_flags. Reviewed By: scott.linder Differential Revision: https://reviews.llvm.org/D84519
