--- Comment #1 from Chris Lattner <clattner at apple.com> ---
Perhaps it depends on the object format, but these get uniqued by the linker. 
On darwin, for example, these get emitted to the:
"__TEXT,__literal4,4byte_literals" section, which does this.

Given this, and given issues with displacement limitations, it doesn't make
sense to tackle this in the compiler.  The linker is a better place to solve
this.
