00e08fcaa0 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

b1c8844101 Add support for hashing location information for CU level hashes.
Add a testcase based on sret.cpp where we can now hash the entire
compile unit.

31dd38ed2f 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.

f1545a2197 DWARF type hashing: begin implementing Step 5, summary hashing in declarable contexts
There are several other tag types that need similar handling but to
ensure test coverage they'll be coming incrementally.

3baa3c37ce 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.

examples.

55c06ae7af Revert "Give internal classes hidden visibility."
It works with clang, but GCC has different rules so we can't make all of those
hidden. This reverts commit r190534.

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.

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.
