RFR (XS) 8200608: Build failures after JDK-8191101 (Show register content in hs-err file on assert)

[Aleksey Shipilev]

Bug:
 https://bugs.openjdk.java.net/browse/JDK-8200608

"jlong" is not "intx" in x86_32. The fix is simple, because os::current_thread_id() actually returns
intx. I think the fix falls under triviality rule.

Testing: x86_32 and x86_64 builds
