We get this output machine code for x86_64:
_testFunc: ## @testFunc
.cfi_startproc
## BB#0: ## %entry
pushq %rax
Lcfi0:
.cfi_def_cfa_offset 16
callq _getCode
callq *%rax
Ltmp0:
popq %rax
retq
Without the deopt operand bundle:
_testFunc: ## @testFunc

## BB#0: ## %entry
pushq %rax
Lcfi0:
.cfi_def_cfa_offset 16
callq _getCode
callq *%rdx...
