ELF: Create synthetic sections for loadable partitions. We create several types of synthetic sections for loadable partitions, including: - The dynamic symbol table. This allows code outside of the loadable partitions to find entry points with dlsym. - Creating a dynamic symbol table also requires the creation of several other synthetic sections for the partition, such as the dynamic table and hash table sections. - The partition's ELF header is represented as a synthetic section in the combined output file, and will be used by llvm-objcopy to extract partitions.
