This is to fix two issues related with loading address: 1) When multiple MMAPs occur and their loading address are different, before it only used the first MMap as base address, all perf address after it used the wrong base address. 2) For pseudo probe profile, the address is always based on preferred loading address. If the base address is not equal to the preferred loading address, the pseudo probe address query will be wrong. Solution: Instead of converting the address to offset lazily, right now all the address after parsing are converted on the fly based on preferred loading address in the parsing time. There is no "offset" used in profile generator any more. Reviewed By: hoy, wenlei Differential Revision: https://reviews.llvm.org/D126827
