Dale Johannesen dd224d2333 Massive rewrite of MMX:
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.

Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics. 

MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces.  Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.

The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.

Bill Wendling e26fffc597 Auto-upgrade the magic ".llvm.eh.catch.all.value" global to
"llvm.eh.catch.all.value". Only the name needs to be changed.

Bob Wilson f65c9ef720 Replace NEON vabdl, vaba, and vabal intrinsics with combinations of the
vabd intrinsic and add and/or zext operations.  In the case of vaba, this
also avoids the need for a DAG combine pattern to combine vabd with add.
Update tests.  Auto-upgrade the old intrinsics.

Bob Wilson 38ab35a911 Remove NEON vmull, vmlal, and vmlsl intrinsics, replacing them with multiply,
add, and subtract operations with zero-extended or sign-extended vectors.
Update tests.  Add auto-upgrade support for the old intrinsics.

Bob Wilson 4cd8a126c3 Remove NEON vmovn intrinsic, replacing it with vector truncate operations.
Auto-upgrade the old intrinsic and update tests.

Bob Wilson d0c054886c Remove NEON vaddl, vaddw, vsubl, and vsubw intrinsics. Instead, use llvm
IR add/sub operations with one or both operands sign- or zero-extended.
Auto-upgrade the old intrinsics.

Bob Wilson edf722add3 Add alignment arguments to all the NEON load/store intrinsics.
Update all the tests using those intrinsics and add support for
auto-upgrading bitcode files with the old versions of the intrinsics.

zero-extend operations.

Chris Lattner c239eb79bd reapply 'reject forward references to functions whose type don't match'
now that the testsuite has been updated.

Eric Christopher 64831c6a4c Remove the palignr intrinsics now that we lower them to vector shuffles,
shifts and null vectors. Autoupgrade these to what we'd lower them to.

Add a testcase to exercise this.

Mon P Wang c576ee9040 Reapply address space patch after fixing an issue in MemCopyOptimizer.
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Eric Christopher 6ad8167714 Remove the pmulld intrinsic and autoupdate it as a vector multiply.
Rewrite the pmulld patterns, and make sure that they fold in loads of
arguments into the instruction.

Dan Gohman 00f4747bad Fix the bitcode reader to deserialize nuw/nsw/etc. bits properly in the case
of a forward-reference, which doesn't use an "abbrev" encoding.

Dan Gohman 1880092722 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead
of using llvm-as, now that opt supports this.
