RDF: Copy propagation

This is a very limited implementation of DFG-based copy propagation.
It only handles actual COPY instructions (does not handle other equivalents
such as add-immediate with a 0 operand).
The major limitation is that it does not update the DFG: that will be the
change required to make it more robust (hopefully coming up soon).

objects (i.e. when reusing the same pass manager to create multiple object
files):
1) AttributeSection needs to be reset to nullptr, because otherwise the backend
   will try to emit into the old object file's attribute section causing a
   segmentation fault.
2) MappingSymbolCounter needs to be reset, otherwise the second object file
   will start where the first one left off.
3) The MCStreamer base class resets the Streamer's e_flags settings. Since
   EF_ARM_EABI_VER5 is set on streamer creation, we need to set it again
   after the MCStreamer was rest.

Also rename Reset (uppser case) to EHReset to avoid confusion with
reset (lower case).

(a zero-extended 64-bit load).

the lower 64 bits of the input to a 128-bit vcvtph2ps are used.  This means
the instruction combiner will ordinarily optimize away the upper 64-bit

[IRMover] Don't copy personality, etc unless creating def

Function::copyAttributesFrom will copy the personality function, prefix
data and prolog data from the source function to the new function, and
is invoked when the IRMover copies the function prototype. This puts a
reference to a constant in the source module on a function in the dest
module, which causes an error when deleting the source module after
importing, since the personality function in the source module still has
uses (this would presumably also be an issue for the prologue and prefix

prototype, as they are mapped properly when/if we link the function body.

[sanitizer] [msan] Fix origin store of array types

This patch fixes the memory sanitizer origin store instrumentation for
array types.  This can be triggered by cases where frontend lowers
function return to array type instead of aggregation.

For instance, the C code:

--
struct mypair {
 int64_t x;
 int y;
};

mypair my_make_pair(int64_t x, int y)  {
 mypair p;
 p.x = x;
 p.y = y;
 return p;
}

int foo (int p)
{
  mypair z = my_make_pair(p, 0);
  return z.y + z.x;
}
--

It will be lowered with target set to aarch64-linux and -O0 to:

--
[...]
define i32 @_Z3fooi(i32 %p) #0 {
[...]
%call = call [2 x i64] @_Z12my_make_pairxi(i64 %conv, i32 0)
%1 = bitcast %struct.mypair* %z to [2 x i64]*
store [2 x i64] %call, [2 x i64]* %1, align 8
[...]
--

The origin store will emit a 'icmp' to test each store value again the
TLS origin array.  However since 'icmp' does not support ArrayType the
memory instrumentation phase will bail out with an error.

This patch change it by using the same strategy used for struct type on
array.

It fixes the 'test/msan/insertvalue_origin.cc' for aarch64 (the -O0 case).
