Summary: This commit introduces a new AMDGPUPALMetadata class that: * is inside the AMDGPU target; * keeps an in-memory representation of PAL metadata; * provides a method to read the frontend-supplied metadata from LLVM IR; * provides methods for the asm printer to set metadata items; * provides methods to write the metadata as a binary blob to put in a .note record or as an asm directive; * provides a method to read the metadata as a binary blob from a .note record. Because llvm-readobj cannot call directly into a target, I had to remove llvm-readobj's ability to dump PAL metadata, pending a resolution to https://reviews.llvm.org/D52821 Differential Revision: https://reviews.llvm.org/D57027 Change-Id: I756dc830894fcb6850324cdcfa87c0120eb2cf64 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@356582 91177308-0d34-0410-b5e6-96231b3b80d8
