Hmm, does combination of PRESERVE hack and the gimplifier change gets the
testsuite
clean and both LTO/WHOR working?
You can construct a testcase where you have two source units both having thread
local
variables with uses all intlined into main(). This is case where I think the
DECL_PRESERVE hack should fall appart.
