DIEHash: Use DW_FORM_sdata for integers, per spec.
...
This allows us to produce the same hash as GCC for at least some simple
examples.

Add a hashing routine that handles hashing types. Add a test for
...
hashing the contents of DW_FORM_data1 on top of a type with attributes.

Add the rest of the stock attributes to the attribute table.
...
This won't affect the kinds of hashes we test for as we actually
do hashing based on form and attribute. Change the fission-hash
testcase one last time to handle DW_AT_comp_dir.

algorithm. Update the split dwarf hashing testcase accordingly - this
should be the last time that the hash of an empty file changes.

Pass DIEHash::collectAttributes output argument by-pointer instead of by-value.

Before this, collectAttributes() was operating on a local object.

Add the start of DIE hashing for DWARF4 type units and split dwarf
...
CUs.
Currently only hashes the name of CUs and the names of any children,
but it's an obvious first step to show the framework. The testcase
should continue to be correct, however, as it's an empty TU.
