have a SINGLE backedge. This is useful to, for example, the -indvars pass.
This implements testcase LoopSimplify/single-backedge.ll and closes PR#34

* Print floating point values using C99 hexadecimal style FP if possible.
This increases the number of floating point constants that may be emitted
inline, and improves precision for global variable initializers which
can not be emitted in integer form.
This fixes the Olden/Power benchmark with the CBE!!!!

* Fix isFPCSafeToPrint to find more constants safe to print, which it was
failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
time. This has the advantage of allowing us to emit constants at global
scope instead of function scope. This speeds FP programs quite a bit.

try to understand it; maybe this will help someone else do so too.
Default CVSRootDir to $CVSROOT first, then the path in ~vadve only if $CVSROOT
was not set.
Checkout with -z3 if we might be checking out over ssh/rsh.
Check the filename of gnuplot to see if it is executable; if not, as a
last resort, try just plain "gnuplot", hoping it is in the path somewhere.
Remove a little extra whitespace.

I don't remember precisely what bug this fixed, but I remember that
it fixed a bug. Sorry. (I think one of these args had a Funny Shell Character
in it, or a space, or something, in my last build, and this seemed
like the obvious fix.)

Dead.
This is a dead header.
It's not pining! It's passed on! This header is no more! It has ceased
to be! It's expired and gone to meet its maker! It's a stiff! Bereft
of life, it rests in peace! If you hadn't nailed it to the perch it'd
be pushing up the daisies! Its metabolic processes are now history! It's
off the twig! It's kicked the bucket! It's shuffled off its mortal coil,
run down the curtain, and joined the bleeding choir invisibile!! THIS IS
AN EX-HEADER!!

In lookupFunction():
Change to use "F" for Function argument instead of ancient "M".
Remove commented-out code.
Change to use GetAddressOfSymbol instead of dlsym.
