Rafael Espindola 2532431332 Stop propagating Entsize. 
Now that we combine multiple synthetic merge section into one output
section there is no point in trying to propagate a value.

Rafael Espindola 0b9531c8e6 Bring r267164 back with a fix. 
The fix is to handle local symbols referring to SHF_MERGE sections.

Original message:

GC entries of SHF_MERGE sections.

It is a fairly direct extension of the gc algorithm. For merge sections
instead of remembering just a live bit, we remember which offsets
were used.

This reduces the .rodata sections in chromium from 9648861 to 9477472
bytes.
