  Changed paths:
    M llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp

    M llvm/test/Transforms/SLPVectorizer/X86/inst_size_bug.ll

  Log Message:
  -----------
  [SLP]Improve and fix getVectorElementSize.

1. Need to cleanup InstrElementSize map for each new tree, otherwise might
use sizes from the previous run of the vectorization attempt.
2. No need to include into analysis the instructions from the different basic
   blocks to save compile time.
