review request (S/M): 6951319 enable Sun Studio 12 update 1

[David Holmes]

John,

First a dumb question :) Are the .il files only used with SunStudio?

For the dtrace tail-call problem won't this:

+ // Work around dtrace tail call bug 6672627 until it is fixed in 
solaris 10.
+ #define HS_DTRACE_WORKAROUND_TAIL_CALL_BUG() \
+   do { volatile size_t dtrace_workaround_tail_call_bug = 1; } while (0)

be elided by any decent compiler - even though volatile it is a local 
and so the assignment is vacuous ?
