c5f49f8e59 Add a 'zkill' script, which is more-or-less a fancy (although not necessarily 
very robust) version of killall. Because I like making shiny new wheels out of
spare parts.

For use by buildbots when people insist on making cc1 infinite loop. :)

6c67b00026 Teach an instcombine to not pull trunc instructions through PHI nodes 
when both the source and dest are illegal types, since it would cause
the phi to grow (for example, we shouldn't transform test14b's phi to
a phi on i320).  This fixes an infinite loop on i686 bootstrap with
phi slicing turned on, so turn it back on.

1543f2c26f Speculatively revert r8644[3-5], they seem to be leading to infinite loops in 
llvm-gcc bootstrap.

7b3a35eee8 It is invalid to infer the value type from the result #0 of the node 
since the instruction might use the other result of different type.

bbee468b71 Derive the right paths to use during testing instead of passing it in via make. 
Also, fix a few other details of the cmake test target and rename it to
'check'. CMake tests now work for the most part, but there are a handful of
failures left due to missing site.exp bits.

cddc8aa1b8 teach a couple of instcombine transformations involving PHIs to 
not turn a PHI in a legal type into a PHI of an illegal type, and
add a new optimization that breaks up insane integer PHI nodes into
small pieces (PR3451).

49d93dc6d1 x86 vector shuffle cleanup/fixes: 
1. rename the movhp patfrag to movlhps, since thats what it actually matches
2. eliminate the bogus movhps load and store patterns, they were incorrect.  The load transforms are already handled (correctly) by shufps/unpack.
3. revert a recent test change to its correct form.

c6bb31e5ea make instcombine only rewrite a chain of computation 
(eliminating some extends) if the new type of the
computation is legal or if both the source and dest
are illegal.  This prevents instcombine from changing big
chains of computation into i64 on 32-bit targets for 
example.

31e2c18379 all targets should be required to declare legal integer types. My plan to 
make it optional doesn't work out.  If you don't want to specify this, don't
specify a TD string at all.
