Add support for hashing attributes with DW_FORM_block. This required
...
passing down an AsmPrinter instance so we could compute the size of
the block which could be target specific. All of the test cases in
the unittest don't have any target specific data so we can use a NULL
AsmPrinter there. This also depends upon block data being added as
integers.
We can now hash the entire fission-cu.ll compile unit so turn the
flag on there with the hash value.

DWARF type hashing: Handle multiple (including recursive) references to the same type
...
This uses a map, keeping the type DIE numbering separate from the DIEs
themselves - alternatively we could do things the way GCC does if we
want to add an integer to the DIE type to record the numbering there.

Revert "Give internal classes hidden visibility."

It works with clang, but GCC has different rules so we can't make all of those
