[DirectX] Simplify and correct the flattening of GEPs in DXILFlattenArrays (#146173)
In tandem with #146800, this PR fixes #145370
This PR simplifies the logic for collapsing GEP chains and replacing
GEPs to multidimensional arrays with GEPs to flattened arrays. This
implementation avoids unnecessary recursion and more robustly computes
the index to the flattened array by using the GEPOperator's
collectOffset function, which has the side effect of allowing "i8 GEPs"
and other types of GEPs to be handled naturally in the flattening /
collapsing of GEP chains.
Furthermore, a handful of LLVM DirectX CodeGen tests have been edited to
fix incorrect GEP offsets, mismatched types (e.g., loading i32s from a
an array of floats), and typos.
