[InstCombine][CmpInstAnalysis] Use consistent spelling and function names. NFC. (#171645) Both `decomposeBitTestICmp` and `decomposeBitTest` have a parameter called `lookThroughTrunc`. This was spelled in full (i.e. `lookThroughTrunc`) in the header. However, in the implementation, it's written as `lookThruTrunc`. I opted to convert all instances of `lookThruTrunc` into `lookThroughTrunc` to reduce surprise while reading the code and for conformity. --- The other change in this PR is the renaming of the wrapper around `decomposeBitTest()`. Even though it was a wrapper around `CmpInstAnalysis.h`'s `decomposeBitTest`, the function was called `decomposeBitTestICmp`. This is quite confusing because such a function _also_ exists in `CmpInstAnalysis.h`, but it is _not_ the one actually being used in `InstCombineAndOrXor.cpp`.
