Remove DeclSpec::Invalid, a recently added bool that allowed the parser to detect if the decl spec was invalid.

For now, we will stick with the original strategy - clients of Parse::ParseDeclarationSpecifiers() should never have to know this.

branch ALWAYS be the last successor for a switch-terminated block. This allows
clients to distinguish cases like the following:

switch(...)
  case XXX:
    switch(...) {
      case YYY: ...
    }
    
  case ZZZ: ..
}

In this case, the block with "case ZZZ:" is the default block for the inner
switch statement, but that case is associated with the outer switch statement,
and not the inner one. Clients can test for this behavior by checking if a
successor block is the last one (and thus just assume that this is the "default"
case).

"default" case. In such cases, we now correctly add the CFGBlock representing
the code after the switch statement as a successor to the block terminated by
the switch statement.

CTTZ and CTPOP.  The expansion code differs from
that in LegalizeDAG in that it chooses to take the
CTLZ/CTTZ count from the Hi/Lo part depending on
whether the Hi/Lo value is zero, not on whether
CTLZ/CTTZ of Hi/Lo returned 32 (or whatever the
width of the type is) for it.  I made this change
because the optimizers may well know that Hi/Lo
is zero and exploit it.  The promotion code for
CTTZ also differs from that in LegalizeDAG: it
uses an "or" to get the right result when the
original value is zero, rather than using a compare
and select.  This also means the value doesn't
need to be zero extended.

Renamed class GRConstants => GRExprEngine.

This was done with a Perl script, and will result in 80 col. violations that
I will gradually fix up.

tgmath.h.

Note that there is another issue with tgmath.h, so mandel.c still 
doesn't work.
