Simplify handling of shifts to be the same as we do for adds. Add support
...
for (X * C1) + (X * C2) (where * can be mul or shl), allowing us to fold:
Y+Y+Y+Y+Y+Y+Y+Y
into
%tmp.8 = shl long %Y, ubyte 3 ; <long> [#uses=1]
instead of
%tmp.4 = shl long %Y, ubyte 2 ; <long> [#uses=1]
%tmp.12 = shl long %Y, ubyte 2 ; <long> [#uses=1]
%tmp.8 = add long %tmp.4, %tmp.12 ; <long> [#uses=1]
This implements add.ll:test25
Also add support for (X*C1)-(X*C2) -> X*(C1-C2), implementing sub.ll:test18

Fold:
...
(X + (X << C2)) --> X * ((1 << C2) + 1)
((X << C2) + X) --> X * ((1 << C2) + 1)
This means that we now canonicalize "Y+Y+Y" into:
%tmp.2 = mul long %Y, 3 ; <long> [#uses=1]
instead of:
%tmp.10 = shl long %Y, ubyte 1 ; <long> [#uses=1]
%tmp.6 = add long %Y, %tmp.10 ; <long> [#uses=1]

Tune compression:
...
bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed
or compression ratio on all but the largest bytecode files (>1MB)
zip: level 9 -> 6, this speeds up compression time by ~30% but only
degrades the compressed size by a few bytes per megabyte. Those few
bytes aren't worth the effort.
