724bea90b0 Remove this code for now. I have a better idea and will rewrite with 
that in mind.

5ba8bf6d28 When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

744f579b63 An empty global constant (one of size 0) may have a section immediately 
following it. However, the EmitGlobalConstant method wasn't emitting a body for
the constant. The assembler doesn't like that. Before, we were generating this:

  .zerofill __DATA, __common, __cmd, 1, 3

This fix puts us back to that semantic.

4633306844 From PR6228: 
"Attached patch removes the extra NUL bytes from the output and changes
test/Archive/MacOSX.toc from a binary to a text file (removes
svn:mime-type=application/octet-stream and adds svn:eol-style=native).  I can't
figure out how to get SVN to include the new contents of the file in the patch
so I'm attaching it separately."

Patch by James Abbatiello!

ea4b6dfd8f Rework constant expr and array handling for objectsize instcombining. 
Fix bugs where we would compute out of bounds as in bounds, and where
we couldn't know that the linker could override the size of an array.

Add a few new testcases, change existing testcase to use a private
global array instead of extern.

12ce0de462 Added support for X86 instruction prefixes so llvm-mc can assemble them. The 
Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.

82a5946939 Added another version of the X86 assembler matcher test case. 
This test case is different subset of the full auto generated test case, and a
larger subset that is in x86_32-bit.s (that set will encode correctly).  These
instructions can pass though llvm-mc as it were a logical cat(1) and then
reassemble to the same instruction.  It is useful as we bring up the parser and
matcher so we don't break things that currently work.
