f2124cc6c1 When folding a load from a global constant, if the load started in the middle
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.

de4a127470 Eliminate the stack slot used to save the global base register.
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.

cde227bc2a In order to correctly compile
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.

16b7dd64e9 Fix a bug in the x86 disassembler's symbolic disassembly support for Jcc-Jump
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

23a62cbaf5 ELF does not imply GNU/Linux. Do not assume GNU conventions just because we
are targeting an ELF platform.  Only fold gs-relative (and fs-relative) loads
if it is actually sensible to do so for the target platform.

This fixes PR13438.

might be deliberate "one time" leaks, so that leak checkers can find them.

code I thought I was committing last time; the I->eraseFromParent() goes
*after* the break out of the loop.
