Stephen Tozer addf1c9711 Do not treat llvm.fake.use as a debug instruction (#128684) 
The llvm.fake.use intrinsic is used to prevent certain values from being
optimized out for the benefit of debug info; it is not, however, a debug
or pseudo instruction itself and necessarily must not be treated as one,
since its purpose is to act like a normal instruction. In the original
commit that added them, the IR intrinsic however was treated as one in
`getPrevNonDebugInstruction` (but _not_ in `getNextNonDebugInstruction`,
or in the MIR equivalents). This patch correctly treats it as a
non-debug instruction.

(cherry picked from commit af68927a831c45b92248b1f6fc24d445be42dd91)
