Stephen Tozer 757a0e6d3b [SystemZ] Treat FAKE_USE instructions as instructions without a size (#144390)
This patch fixes an error in which `FAKE_USE` instructions would trigger
an assertion in SystemZLongBranch due to them having a size of 0 without
being excepted in the assertion that each instruction, other than a set
of known 0-size instruction types, should have a non-0 size.

`FAKE_USE` instructions are no-op instructions that are emitted into
LLVM by the `-fextend-variable-liveness` clang flag to help preserve the
liveness of source variables in optimized code, and therefore they
should be understood as being valid size 0 instructions.
