c1e4e3743b Allow copyRegToReg to emit cross register classes copies. 
Tested with "make check"!

5e1a428344 Move the setOperationAction(ISD::DEBUG_LOC, MVT::Other, Expand) and 
the check to see if the assembler supports .loc from X86TargetLowering
into the superclass TargetLowering.

5924bf7d3b Added major new capabilities to scheduler (only BURR for now) to support physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered.

4230512f32 Change APFloat::convertFromInteger to take the incoming 
bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers.  Add const to one of the APInt constructors
to prevent surprising match when called with const
argument.

69833b61ac The exception handling function info should be reset for each new 
function. The information isn't used heavily -- it's only used at the end
of exception handling emission -- so there's no need to cache it.

067f1d8e95 Objective-C was generating EH frame info like this: 
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

98d3a08d8f Remove the assumption that FP's are either float or 
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

33a7f51412 1. Don't call Value::getName(), which is slow. 
2. Lower calls to fabs and friends to FABS nodes etc unless the function has
   internal linkage.  Before we wouldn't lower if it had a definition, which
   is incorrect.  This allows us to compile:

define double @fabs(double %f) {
        %tmp2 = tail call double @fabs( double %f )
        ret double %tmp2
}

into:

_fabs:
        fabs f1, f1
        blr

bed9dc423c Next round of APFloat changes. 
Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
