Hi,
please review small fix for 8209439: C2 library_call can potentially
ignore Math.pow intrinsic or use null pointer
During development of Math.pow intrinsic for AArch64 I noticed, that
this intrinsic is not used, so I found copy-paste error in library
calls. dexp existence is checked instead of dpow while trying to inline
Math.power.
Currently no platform is affected because dexp and dpow either both
missing or exists.
I've verified this fix by compiling jdk with my intrinsic and checking
vm behavior (on AArch64).

Thanks,
