7e071e14eb Revert previous change to a comment. The BlockAddresses go in the 
constant pool so they don't get wrapped separately.

disable it until I can fix it.

0668ac893d Chain dependencies used to enforce memory order should have latency of 0 (except for true dependency of Store followed by aliased Load... we estimate that case with a single cycle of latency assuming the hardware will bypass)

ec5cb0cdbd Initilize the machine LICM CSE map upon the first time an instruction is hoisted to 
the loop preheader. Add instructions which are already in the preheader block that
may be common expressions of those that are hoisted out. These does get a few more
instructions CSE'ed.

f1afb57935 improve IPSCCP to be able to propagate the result of "!mayBeOverridden" 
function to calls of that function, regardless of whether it has local
linkage or has its address taken.  Not escaping should only affect 
whether we make an aggressive assumption about the arguments to a 
function, not whether we can track the result of it.

16b825e51f Use the libanalysis 'ConstantFoldLoadFromConstPtr' function 
instead of reinventing SCCP-specific logic.  This gives us
new powers.

32acebedf7 switch the main 'ValueState' map from being an std::map to being 
a DenseMap.  Doing this required being aware of subtle iterator
invalidation issues, but it provides a big speedup.  In a 
release-asserts build, this sped up optimizing 403.gcc from
1.34s -> 0.79s (IPSCCP) and 1.11s -> 0.44s (SCCP).

This commit also conflates in a bunch of general cleanups, sorry.

9737bfedeb Do not infer the target type for COPY_TO_REGCLASS from dest regclass, this won't work if it can contain several types. Require explicit result type for the node for now. This fixes PR5364. 
PS: It seems that blackfin usage of copy_to_regclass is completely bogus!
