Soby Mathew f1722b693d PIE: Use PC relative adrp/adr for symbol reference This patch fixes up the AArch64 assembly code to use adrp/adr instructions instead of ldr instruction for reference to symbols. This allows these assembly sequences to be Position Independant. Note that the the reference to sizes have been replaced with calculation of size at runtime. This is because size is a constant value and does not depend on execution address and using PC relative instructions for loading them makes them relative to execution address. Also we cannot use `ldr` instruction to load size as it generates a dynamic relocation entry which must not be fixed up and it is difficult for a dynamic loader to differentiate which entries need to be skipped.
