Manman Ren 062986c2f0 PGO: preserve branch-weight metadata when simplifying two branches with a common
destination.

Updated previous implementation to fix a case not covered:
// PBI: br i1 %x, TrueDest, BB
// BI:  br i1 %y, TrueDest, FalseDest
The other case was handled correctly.
// PBI: br i1 %x, BB, FalseDest
// BI:  br i1 %y, TrueDest, FalseDest

Also tried to use 64-bit arithmetic instead of APInt with scale to simplify the
computation. Let me know if you have other opinions about this.
