to multiply the instruction count by a constant factor in a few places, which
caused the register allocator to require many more iterations.

This fixes several recent CBE regressions.

Refine the error message of unused ivars.
Added test case.

When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.
This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

Added ObjCIvarDecl::getCanonicalAccessControl() to report the visible access
control of an ivar, whereas getAccessControl() returns the access control
relating to how the ivar was actually declared.

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

they appear in words. This would cause things like the "128" in "VR128"
to be highlighted. This patch fixes the highlighting by only recognizing 
constants when they have word breaks around them.'

Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.
