6e800fe6cb The InReg parameter attribute is valid on function results. The llvm-gcc-4.0 
front end converts regparm attribute on the gcc function into InReg attribute 
on the llvm function. This fixes test/CFrontend/2002-07-30-SubrefSetAssertion.c

9d3e79107d It seems logical that InReg should be incompatible 
with StructReturn and ByVal, so make it so.

fdef00f1f7 As the number of parameter attributes increases, 
Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes.  This patch tidies the whole thing up
using attribute masks.  While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail.  Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).

552d6405bf Add better verification of attributes on function types. It is not permitted 
to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.

9445e9aaa0 For PR1553: 
Change the keywords for the zext and sext parameter attributes to be 
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.

7f32156bb9 Generalize MVT::ValueType and associated functions to be able to represent 
extended vector types. Remove the special SDNode opcodes used for pre-legalize
vector operations, and the special MVT::Vector type used with them. Adjust
lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.

This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.
