RFR(XXS/M): 8193135 - get rid of redundant _smr_ prefix/infix in ThreadSMRSupport stuff

[Daniel D. Daugherty]

Greetings,

This should be last of the big Thread-SMR cleanup reviews! Stefan K, this
is one of your Thread-SMR follow-up suggestions so I need to hear from you
on this thread. Thanks!

In terms of actual "new/changed" code, this is an "XXS" review. However,
because of renaming, the changed/insert/delete counts are the size of an
"M" review. This is another simple (but tedious) review; I found that
the "udiffs" were easier than "frames" to verify the fix.

Here is the bug:

     JDK-8193135 get rid of redundant _smr_ prefix/infix in 
ThreadSMRSupport stuff
     https://bugs.openjdk.java.net/browse/JDK-8193135

Here is the full webrev:

Because of the removal of the '_smr_' prefix/infix, some functions had
to be moved to stay in proper sort order. I've created separate delta
webrevs to separate the renaming from the code motion.

Here is the renaming part of the review:

http://cr.openjdk.java.net/~dcubed/8193135-webrev/jdk10-0-delta-part1/

Here is the code motion part of the review:

http://cr.openjdk.java.net/~dcubed/8193135-webrev/jdk10-0-delta-part2/

This fix is being (over) tested with a Mach5 tier[1-5] run.

The code motion part was sanity checked by extracting the pre-move code
into a file, extracting the post-move code into another file and comparing
the two files. I didn't come up with a good way to automate the sanity
checking of the removal of the '_smr_' prefix/infix; that was complicated
by the fact that the two 'smr_delete()' functions were not renamed to
'delete()'.

Thanks, in advance, for any comments, questions or suggestions.

Dan
