  Bitcode: Stop combining function alignments into MaxAlignment.

MaxAlignment is used to produce the abbreviation for MODULE_CODE_GLOBALVAR
and is not used for anything related to function alignments, so stop
combining function alignments and rename it to make its purpose clearer.

  [SCEV] Try to push op into ZExt: C * zext (A + B) -> zext (A*C + B*C) (#155300)

Try to push constant multiply operand into a ZExt containing an add, if
possible. In general we are trying to push down ops through ZExt if
possible. This is similar to
https://github.com/llvm/llvm-project/pull/151227 which did the same for
additions.

For now this is restricted to adds with a constant operand, which is
similar to some of the logic above.

This enables some additional simplifications.

  [CIR] Add VTTAddrPointOp (#155048)

This adds the definition, verification, and lowering for CIR's
VTTAddrPointOp. This is a bit ahead of the current codegen
implementation, which doesn't yet have support for emitting VTT
definitions, but since this doesn't depend on any of the other work in
progress, it is being upstreamed in advance.
