warning: enumeration values 'AllocatedPointer' and 'AllocAlign' not handled in switch

[est31]

On recent master, compiling gives me this warning in stdout:

warning: llvm-wrapper/RustWrapper.cpp:159:11: warning: enumeration values 'AllocatedPointer' and 'AllocAlign' not handled in switch [-Wswitch]
warning:   switch (Kind) {
warning:           ^
warning: 1 warning generated.

Now, they are handled in the switch case, but are gated by LLVM_VERSION_GE. I think this is a fall out of #99574. The issue is probably fixed by adding similar gating to LLVMWrapper.h .
