d49591cf21 Have the X86 back-end emit the alias instead of what's being aliased. In most 
cases, it's much nicer and more informative reading the alias.

4b667cd995 Vectors with different number of elements of the same element type can have 
the same allocation size but different primitive sizes(e.g., <3xi32> and
<4xi32>).  When ScalarRepl promotes them, it can't use a bit cast but
should use a shuffle vector instead.

920274b4dd Passing unroll parameters (unroll-count, threshold, and partial unroll) via LoopUnroll class's ctor. Doing so 
will allow multiple context with different loop unroll parameters to run.  This is a minor change and no effect 
on existing application.

6980d004ee Load multiple object files and link them via RuntimeDyld in llvm-rtdyld. 
Relocations between the object modules are properly resolved, as in the
following trivial example:

$ cat t.c
int foo();
int main() {
    return foo();
}
$ cat foo.c
int foo() {
    return 65;
}
$ clang -c t.c -fno-asynchronous-unwind-tables
$ clang -c foo.c -fno-asynchronous-unwind-tables
$ llvm-rtdyld t.o foo.o ; echo $?
loaded '_main' at: 0x10015c000

e188ff81dd Export LLVM_TARGETS_WITH_JIT in LLVMConfig.cmake.in. Without this, 
component names such as "engine" do not expand to "jit" and hence to
the native target libraries for external users.

37f1db39c4 Fix an obvious problem with an alignment computation. AsmPrinter actually does 
the max itself, so it is not easy to write a test case for this, but I added a
test case that would fail if the code in AsmPrinter were removed.

916e01c917 Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency. 
Additional fixes:
Do something reasonable for subtargets with generic
itineraries by handle node latency the same as for an empty
itinerary. Now nodes default to unit latency unless an itinerary
explicitly specifies a zero cycle stage or it is a TokenFactor chain.

Original fixes:
UnitsSharePred was a source of randomness in the scheduler: node
priority depended on the queue data structure. I rewrote the recent
VRegCycle heuristics to completely replace the old heuristic without
any randomness. To make the ndoe latency adjustments work, I also
needed to do something a little more reasonable with TokenFactor. I
gave it zero latency to its consumers and always schedule it as low as
possible.

b2c47a2087 Add @earlyclobber constraints to the writeback register of all ARM store instructions. 
The ARMARM specifies these instructions as unpredictable when storing the
writeback register. This shouldn't affect code generation much since storing a
pointer to itself is quite rare.

f288e23b3f This mechanical patch moves type handling into CompileUnit from DwarfDebug. In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious.

f9c9d3e05b Remove the unaligned load intrinsics in favor of using native unaligned loads. 
Now that we have a first-class way to represent unaligned loads, the unaligned
load intrinsics are superfluous.
