.comm _X,0

For X, which makes the linker thing that X is never defined.

4d234c23f1 Get rid of subbullets for all of the "known problems" section. None of the

Also, fix a bug where ubyte 255 would sometimes be output as -1. This
was afflicting hbd.

97adae1fa4 Though the previous xform applies to literally dozens (hundreds?) of variables 
in SPEC, the subsequent optimziations that we are after don't play with
with FP values, so disable this xform for them.  Really we just don't want
stuff like:

double G;   (always 0 or 412312.312)
  = G;

turning into:

bool G_b;
  = G_b ? 412312.312 : 0;

We'd rather just do the load.

f125dc0e49 If a variable can only hold two values, and is not already a bool, shrink it 
down to actually BE a bool.  This allows simple value range propagation
stuff work harder, deleting comparisons in bzip2 in some hot loops.

This implements GlobalOpt/integer-bool.ll, which is the essence of the
loop condition distilled into a testcase.

02c04bbf45 If one side of and/or is known to be 0/-1, it doesn't matter 
if the other side is overdefined.

This allows us to fold conditions like:  if (X < Y || Y > Z) in some cases.
