fc061f4e20 Don't barf on empty basic blocks. Do not rely on assert 
doing something - this needs to work for release builds
too.  I chose to just abort rather than following the
fancy logic of abortIfBroken, because (1) it is a pain
to do otherwise, and (2) nothing is going to work if the
module is this broken.

4618bf2f11 remove verifier command line option: this should be part of the API, not 
a command line optn.

(in hindsight) infinite recursion.  Simplify the code.

a9d080508e Fix a regression in test/CodeGen/X86/2007-04-24-VectorCrash.ll introduced 
by r43510. Gracefully handle constants with vector type that aren't
ConstantVector or ConstantAggregateZero.

1659eb3c3f I am not sure this is a good idea to be an option, but rename the option for 
now.  It conflicts with clang's -pedantic flag.

9d622a6de1 Initial infrastructure for arbitrary precision integer 
codegen support.  This should have no effect on codegen
for other types.  Debatable bits: (1) the use (abuse?)
of a set in SDNode::getValueTypeList; (2) the length of
getTypeToTransformTo, which maybe should be refactored
with a non-inline part for extended value types.

just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

6e01c5df37 convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

2a0b2ab2fc Constant fold int-to-long-double conversions; 
use APFloat for int-to-float/double; use
round-to-nearest for these (implementation-defined,
