Followups: docs patch for the builtin and eh.sjlj.setjmp cleanup to match
longjmp.

Allow targets more controls on what nodes are scheduled by reg pressure, what for latency in hybrid mode.

llvm-svn: 104293

allow target to override it in order to map register classes to illegal
but synthesizable types. e.g. v4i64, v8i64 for ARM / NEON.

llvm-svn: 103854

Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

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)

A update of langref will occur in a subsequent checkin.

Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

"On ARMv6T2 this turns cttz into rbit, clz instead of the 4 instruction
 sequence it is now."

just issues an error for the moment. The front end won't yet generate these
intrinsics for ARM, so this is behind the scenes until complete.

Add memory barrier intrinsic support for ARM. Moving towards adding the atomic operations intrinsics.

Not functionality change yet.

The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.
