4a544a79bd Split the init.trampoline intrinsic, which currently combines GCC's
init.trampoline and adjust.trampoline intrinsics, into two intrinsics
like in GCC.  While having one combined intrinsic is tempting, it is
not natural because typically the trampoline initialization needs to
be done in one function, and the result of adjust trampoline is needed
in a different (nested) function.  To get around this llvm-gcc hacks the
nested function lowering code to insert an additional parent variable
holding the adjust.trampoline result that can be accessed from the child
function.  Dragonegg doesn't have the luxury of tweaking GCC code, so it
stored the result of adjust.trampoline in the memory GCC set aside for
the trampoline itself (this is always available in the child function),
and set up some new memory (using an alloca) to hold the trampoline.
Unfortunately this breaks Go which allocates trampoline memory on the
heap and wants to use it even after the parent has exited (!).  Rather
than doing even more hacks to get Go working, it seemed best to just use
two intrinsics like in GCC.  Patch mostly by Sanjoy Das.

66d1836380 The insertion point for the loads is right before the llvm.eh.exception
call. The call may be in the same BB as the landingpad instruction. If that's
the case, then inserting the loads after the landingpad inst, but before the
extractvalues, causes undefined behavior.

271439053d No need to get fancy inserting a PHI node when the values are stored in stack
slots. This fixes a bug where the number of nodes coming into the PHI node may
not equal the number of predecessors. E.g., two or more landingpad instructions
may require a PHI before reaching the eh.exception and eh.selector instructions.

24fbb5875c Perform the upgrading of the old EH to the new EH in a more sane manner.
Perform the upgrading in steps.

* First, create a map of the invokes to the EH intrinsics.

* Next, take that mapping and determine if the invoke's unwind destination has a
  single predecessor. If not, then create a new empty block to hold the new
  landingpad instruction.

* Create a landingpad instruction into the uwnind destination. Fill it with the
  values from the old selector. Map the old intrinsic calls to the new
  landingpad values (there may be multiple landingpad instructions per instrinic
  call pairs).

* Go through the old intrinsic calls, create a PHI node when necessary, and then
  replace their values with the new values from the landingpad instructions.

* Delete all dead instructions.

* ???

* Profit!

c82a61c6c6 Initial check in that will auto-upgrade the old EH scheme to the new EH scheme.
This upgrade suffers from the problems of the old EH scheme - i.e., that the
calls to llvm.eh.exception() and llvm.eh.selector() can wander off and get
lost. It makes a valiant effort to reclaim these little lost lambs.

This is a first draft, so it hasn't yet been hooked up to the parser.

92e3916c3b Add intrinsics @llvm.arm.neon.vmulls and @llvm.arm.neon.vmullu.* back. Frontends
was lowering them to sext / uxt + mul instructions. Unfortunately the
optimization passes may hoist the extensions out of the loop and separate them.
When that happens, the long multiplication instructions can be broken into
several scalar instructions, causing significant performance issue.

Note the vmla and vmls intrinsics are not added back. Frontend will codegen them
as intrinsics vmull* + add / sub. Also note the isel optimizations for catching
mul + sext / zext are not changed either.

0488fb649a 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.

808bab0169 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.
