075a62519f Add a "loses information" return value to APFloat::convert 
and APFloat::convertToInteger.  Restore return value to
IEEE754.  Adjust all users accordingly.

9e57068854 Rename APFloat::convertToAPInt to bitcastToAPInt to 
make it clearer what the function does.  No functional

bc53ce331a Use template to distinguish between function variants. 
GCC 4.4.0 gives an error on the "int" declaration for example
saying that it has already been declared (using the "short"
one). Using templates here allow the compiler to distinguish
between the function to choose.

Also, "llvm/Support/DataTypes.h" was not included, leading to
error messages about not knowing "uint32_t" for example.

08e60cee90 Remove -disable-fast-isel. Use cl::boolOrDefault with -fast-isel 
instead.

So now: -fast-isel or -fast-isel=true enable fast-isel, and
-fast-isel=false disables it. Fast-isel is also on by default
with -fast, and off by default otherwise.

2561119124 Instead of emitting an implicit use for the super-register of 
X86::CL that was used, emit an EXTRACT_SUBREG from the CL
super-register to CL. This more precisely describes how the
CL register is being used.

3b86d974bc Mark negative-zero-to-int conversion as Inexact, 
since -0.0 can't be represented as an int.

load-and-convert of int 0.  Fixes
ieee.exp/mzero[2356].c in gcc testsuite.

40d00c0979 Be more precise about which conversions of NaNs 
are Inexact.  (These are not Inexact as defined
by IEEE754, but that seems like a reasonable way
to abstract what happens:  information is lost.)
