73ff5120eb Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}

0bb806bd9a Do not put DEBUG() guard around error condition; this must *always* be printed.

2d930034f4 Modified the code so that we exit() with a non-zero value instead of calling 
abort() when we can't open the input filename.  The abort() function generates
a core dump if possible and is meant for handling errors so grand that even the
program knows that debugging is necessary.

96b4beda5c Added an option to TableGen that allows users to specify a directory in which 
to find include files.  TableGen will load include files from this directory if
it cannot find them in the current directory.
This feature was needed for building code inside the object tree (a la autoconf
style).
TODO: Allow for multiple -I options to specify a list of directories to search.

43bf32e86c Added #include <cassert>. In GCC 3.3, we don't get assert() through the other 
language header files like we did under 3.2.1, and we're not grabbing it
through the LLVM header files either.  So just include it directly.
