definition DIE, to make old GDB happy.
We have a regression for old GDB when Clang uses DW_TAG_member to declare
static members inside a class, instead of DW_TAG_variable. This patch will fix
this regression.

TAG_member inside a class to the specification DIE.
Having AT_MIPS_linkage_name on TAG_member caused old gdb (GNU 6.3.50) to
error out. Also gcc 4.7 has AT_MIPS_linkage_name on the specification DIE.

The main lists of debug info metadata attached to the compile_unit had an extra
layer of metadata nodes they went through for no apparent reason. This patch
removes that (& still passes just as much of the GDB 7.5 test suite). If anyone
can show evidence as to why these extra metadata nodes are there I'm open to
reverting this patch & documenting why they're there.

This adds support for LLVM to accept metadata that doesn't include a top level
lexical block in a function. Specifically LLVM couldn't handle this when there
were file changes relating to these blocks. I've updated a few test cases to
ensure other functionality (such as inlining) isn't affected by this change, but
haven't pervasively updated all the test cases.

We weren't encoding boolean constants correctly due to modeling boolean as a
signed type & then sign extending an i1 up to a byte & getting 255.
