Dan Gohman dab249b3b7 Enable hoisting of loads from constant memory by default. In cases where 
they are lowered to instruction sequences more complex than a simple
load, such that CodeGen cannot rematerialize them, a reload from a
spill slot is likely to be cheaper than the complex sequence.

Torok Edwin 9289ae85b4 LICM shouldn't sink/delete debug information. Fix this and add a testcase. 
For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

Dan Gohman 3eee6542f5 Put the LICM of constant GlobalVariables, introduced in r53945, under a 
command-line option, and disable it by default. It introduced performance
regressions because CodeGen is currently not able to remat such loads.

Chris Lattner 967948b4e2 "Allow LICM to sink or lift loads from constant memory. Also add a test 
case for this.

This allows instructions like loads from global variables declared to
be constant to be moved out of loops."

Patch by Stefanus Du Toit!

Reid Spencer eacb7020ec For PR950: 
Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:

1. Make sure llvm-upgrade is run on the source which does the bulk of the
   changes automatically.

2. Change things like "grep 'int'" to "grep 'i32'"

3. In several tests bitcasting caused the same name to be reused in the
   same type plane. These had to be manually fixed. The fix was (generally)
   to leave the bitcast and provide the instruction with a new name. This
   should not affect the semantics of the test. In a few cases, the
   bitcasts were known to be superfluous and irrelevant to the test case
   so they were removed.

4. One test case uses a bytecode file which needed to be updated to the
   latest bytecode format.
