Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.

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.

This makes the JIT work on FreeBSD 5.1-RELEASE. Whee.

Never call setjmp(), longjmp() or strsignal().

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