8430f1ff9a Reverting dtor devirtualization patch. 
_sabre_: it has a major problem: by the time ~Value is run, all of the "parts" of the derived classes have been destroyed
_sabre_: the vtable lives to fight another day

928143423b Commit 44487 broke bootstrap of llvm-gcc-4.2. It is 
not yet clear why, but in the meantime work around the
problem by making less use of readnone/readonly info.

1e2e4972ff Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

94d751995e Add a convenience method for modifying parameter 
attributes.  While there, I noticed that not all
attribute methods returned a pointer-to-constant,
so I fixed that.

3602011bec Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

114968a3e8 Fix PR1816. If a bitcast of a function only exists because of a 
trivial difference in function attributes, allow calls to it to
be converted to direct calls.  Based on a patch by Török Edwin.
While there, move the various lists of mutually incompatible
parameters etc out of the verifier and into ParameterAttributes.h.

and the 'pure' parameter attribute to 'readonly'.

f69444f091 In order for parameter attribute uniquing to make 
any sense it is important that ParamAttr::None gets
treated the same as not supplying an attribute at
all.  Rather than stripping ParamAttr::None out of
the list of attributes, assert if ParamAttr::None
is seen.  Fix up the bitcode reader which liked to
insert ParamAttr::None all over the place.  Patch
based on one by Török Edwin.

cf741eccd6 print a call to a fastcc function as: 
call x86_fastcallcc void @func( i32* %X, i64 0 )
not:
	callx86_fastcallcc  void @func( i32* %X, i64 0 )

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.

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.
