[8u40] RFR (XS): 8059226 : Names of rtm_state_change and unstable_if deoptimization reasons were swapped in 8u40

[Filipp Zhinkin]

Hi,

please review the fix aimed to fix a glitch happened during 8030976 [1] backport
to 8u40, after which names of rtm_state_change and unstable_if deoptimization
reasonswere swapped [2][3], so rtm_state_change trap was loggingin compilation
logas 'unstable_if' and vice versa.

I've fixed order of DeoptReason values declaration so now it matches the order
used in jdk9 and the names order in Deoptimization::_trap_reason_name.
