c6f2f6fbb9 For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias.

b502bdb604 Add a place where I missed using the maximal set. Note that using the maximal 
set this way is _SLOW_.  Somewhere down the line, I'll look at speeding it up.

ea12a06a81 Very first part of a GVN-PRE implementation. It currently performs a bunch of analysis, and nothing more. It is also quite slow for the moment. However, 
it should give a sense of what's going on.

7aea832034 Two tail merging improvements: 
When considering blocks with more than 2 predecessors, merge the block with
the largest number of matching insns, rather than the first block found.
Considering that 1 matching insn is enough to show a win for candidates that
already end with a branch.

84c614d1ac The Intrinsic::getDeclaration function's Tys parameter only contains the 
types of the iAny types involved in the overloaded intrinsic. Thus, we
can't use the argument number as the index but have to count them separately
in order to index Tys correctly. This patch rectifies this situation.
