llvm's integrated assembler cannot handle immediate values which are
calculated with two local labels:
<instantiation>:3:13: error: invalid operand for instruction
clgfi %r14,.Lsie_done - .Lsie_gmap
Workaround this by adding clang specific code which reads the specific
value from memory. Since this code is within the hot paths of the kernel
and adds an additional memory reference, keep the original code, and add
ifdef'ed code.
