rLLD329787 added the stable sorting to SymbolTableBaseSection::postThunkContents. I profiled the Mozilla (response-O0.txt) from lld-speed-test package and found std::stable_sort is showing up in profile results and consuming the 3.1% of the total CPU time in the RelWithDebug build. Total time of postThunkContents is 3.54%, 238ms. This change reduces postTimeContents time to 50ms, making it to take 0.73% of Total CPU time. So, instead of sorting the local part I suggest to just rebuild it. That is what this patch does. Differential revision: https://reviews.llvm.org/D45519 llvm-svn: 335583
