* 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.

tasty 15% speedup on the testcase from Bill.

in practice though

llvm-svn: 8985

changes:
  * BytecodeReader::getType(...) used to return a null pointer
    on error.  This was only checked about half the time.  Now we convert
    it to throw an exception, and delete the half that checked for error.
    This was checked in before, but psmith crashed and lost the change :(
  * insertValue no longer returns -1 on error, so callers don't need to
    check for it.
  * Substantial rewrite of InstructionReader.cpp, to use more efficient,
    simpler, data structures.  This provides another 5% speedup.  This also
    makes the code much easier to read and understand.

simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

llvm-svn: 8983

This results in no significant speedup, but does provide simpler code

llvm-svn: 8980

new, simpler, ForwardReferences data structure.  This is just the first
simple replacement, subsequent changes will improve the code more.

This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement.  This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.
