hopefully make it more visible. Adjust the web-docs to have a link to
this file rather than the list itself. I described code owners as also
being gatekeepers for their part of the code, which I think is true but
isn't in the code owner explanation on the web page.

The generated code for Atom has a different code sequence. This is realted
to commit r160749.

MemoryBuiltins: add support to determine the size of strdup'ed non-constant strings

It is redundant; RegisterCoalescer will do the remat if it can't eliminate
the copy. Collected instruction counts before and after this. A few extra
instructions are generated due to spilling but it is normal to see these kinds
of changes with almost any small codegen change, according to Jakob.
This also fixed rdar://11830760 where xor is expected instead of movi0.

When a live range splits into multiple connected components, we would
arbitrarily assign <undef> uses to component 0. This is wrong when the
use is tied to a def that gets assigned to a different component:
%vreg69<def> = ADD8ri %vreg68<undef>, 1
The use and def must get the same virtual register.
Fix this by assigning <undef> uses to the same component as the value
defined by the instruction, if any:
%vreg69<def> = ADD8ri %vreg69<undef>, 1
This fixes PR13402. The PR has a test case which I am not including
because it is unlikely to keep exposing this behavior in the future.

of an array element (rather than at the beginning of the element) and extended
into the next element, then the load from the second element was being handled
wrong due to incorrect updating of the notion of which byte to load next. This
fixes PR13442. Thanks to Chris Smowton for reporting the problem, analyzing it
and providing a fix.

The long branch pass (fixed in r160601) no longer uses the global base register
to compute addresses of branch destinations, so it is not necessary to reserve
a slot on the stack.

struct s {
double x1;
float x2;
};
__attribute__((regparm(3))) struct s f(int a, int b, int c);
void g(void) {
f(41, 42, 43);
}
We need to be able to represent passing the address of s to f (sret) in a
register (inreg). Turns out that all that is needed is to not mark them as
mutually incompatible.

if Condition Is Met instuctions that was not correctly determining the target
instruction.
So for a jne rel32 instruction:
% cat x.s
.byte 0x0f, 0x85, 0x09, 0x00, 0x00, 0x00
% as x.s
it was incorrectly deterining the target:
% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000 jne 0xd
and with the fix it gets this correct as:
% otool -q -tv a.out
a.out:
(__TEXT,__text) section
0000000000000000 jne 0xf

might be deliberate "one time" leaks, so that leak checkers can find them.
This is a reapply of r160602 with the fix that this time I'm committing the
code I thought I was committing last time; the I->eraseFromParent() goes
*after* the break out of the loop.
