Now PIE is default supported after clang 14. It cause parsing error when using perf2bolt. The reason is the base address can not get correctly. Fix the method of geting base address. If SegInfo.Alignment is not equal to pagesize, alignDown(SegInfo.FileOffset, SegInfo.Alignment) can not equal to FileOffset. So the SegInfo.FileOffset and FileOffset should be aligned by SegInfo.Alignment first and then judge whether they are equal. The .text segment's offset from base address in VAS is aligned by pagesize. So MMapAddress's offset from base address is alignDown(SegInfo.Address, pagesize) instead of alignDown(SegInfo.Address, SegInfo.Alignment). So the base address calculate way should be changed.
