* tree-ssa-alias.c (mem_sym_score): Count call-clobbered
unpartitionable SFTs in the usual way.
(compute_memory_partitions): Do partition call-clobbered
unpartitionable SFTs, but make sure to partition all other
SFTs of its parent var into the same partition.

Confirmed.

void es::ClockAnalyzer::initPrimitives()

is the offending function - yet another testcase with a huge initialization
sequence (we have problems there since long).  This is probably caused by
the fix for PR36339.

In the mean time building with -O1 is fine (the branch has SFTs disabled
there now), and the root of all evil is the fix for PR33870.
