5638dc618a Use the libanalysis 'ConstantFoldLoadFromConstPtr' function 
instead of reinventing SCCP-specific logic.  This gives us
new powers.

2a0433beea 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.

f51635cd30 fix two strange things in the default passmgr: 
1. we'd run simplifycfg at the very start, even though
the per function passes have already cleaned this up.

2. In the main per-function pipeline that is interlaced with inlining 
   etc, we would do instcombine, jump threading, simplifycfg *before*
   doing SROA.  SROA is much more likely to expose opportunities for
   these passes than they are for SROA, so move SRoA up earlier.

also add some comments.

a664bb7bdc when merging two loads, make sure to take the min of their alignment, 
not the max.  This didn't matter until the previous patch because
instcombine would refuse to sink loads with differenting alignments.

e3c6281a98 fix a bug noticed by inspection: when instcombine sinks loads through 
phis, it didn't preserve the alignment of the load.  This is a missed
optimization of the alignment is high and a miscompilation when the
alignment is low.

GlobalOpt already deletes trivially dead functions/globals,
so GlobalDCE only adds values for cycles of dead things.

0037bfabd4 We currently only run ipsccp at LTO time, which is silly. It subsumes 
ipconstprop and doesn't take much time.  Just run it in its place.

This adds a testcase for it, which I plan to expand to cover other
"integration" cases, where we expect the optimizer to be able to
eliminate various things.  Due to phase order issues we've regressed
in a number of areas and integration tests are the only way I see to
prevent this.
