cec7ce78d7 DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0}
A bunch of test cases needed to be cleaned up for this, many my fault -
when implementid imported modules I updated test cases by simply
duplicating the prior metadata field - which wasn't always the empty
metadata entry.

bec50063a5 Debug Info: update testing cases to specify the debug info version number.
We are going to drop debug info without a version number or with a different
version number, to make sure we don't crash when we see bitcode files with
different debug info metadata format.

da39dd30ad DebugInfo: Hash DW_FORM_GNU_str_index as a string.
Found while adding type safety to the various DWARF enumerations (form,
attribute, tag, etc) that caused Clang to warn on an incompletely
covered switch. Converting the comment to a default/unreachable
uncovered this case of an unsupported form encoding. Seems we were
skipping fission strings entirely.

c098708220 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.

bd18c8d090 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.

7ced4fa257 Add support for DW_FORM_dataN and DW_FORM_udata to the DIE hashing
algorithm. Update the split dwarf hashing testcase accordingly - this
should be the last time that the hash of an empty file changes.

15ab9f4aaa Pass DIEHash::collectAttributes output argument by-pointer instead of by-value.
Before this, collectAttributes() was operating on a local object.

0710bfa866 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.
