Make sure that implicit qualification and derived-to-base conversions of xvalues preserve xvalue-ness. Unfortunately I have no idea how to test this property; there doesn't seem to be a syntactical construct that triggers such a conversion and still allows the distinction between prvalues and xvalues to be made.

when the RHS of the ||/&& is ever 0 or 1.  This handles a variety of
creative idioms for "true" used in C programs and fixes many false 
positives at the expense of a few false negatives.  This fixes

Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute().

DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

appropriately-padded main file buffer (that has spaces in the extra
"reserved" space) and thread that buffer through to the parsing
function. This still does nothing.

use of property-dot syntax using 'super' as receiver

that preamble (the preamble text, preamble file, reserved main file
size). Check these details when we try to rebuild the precompiled
preamble, and when nothing has changed, re-use the precompiled
preamble.

This code is still very much a WIP, and can't even properly be tested
because we have no way to use the precompiled preamble yet. "Trust me"

There is no need to use separate dir name for AT_comp_dir attribute. Using absolute path for filename allows clients to query complete file location info from gdb breakpoints. Save constructed full file name.

for vector types, and new functions
has(Signed|Unsigned|)IntegerRepresentation() cover integer types and
vector-of-integer types. This fixes a bunch of latent bugs.
