c93ad7d569 Make load->store deletion a bit smarter. This allows us to compile this: 
void test(long long *P) { *P ^= 1; }

into just:

_test:
	movl	4(%esp), %eax
	xorl	$1, (%eax)
	ret

instead of code like this:

_test:
	movl	4(%esp), %ecx
        xorl    $1, (%ecx)
	movl	4(%ecx), %edx
	movl	%edx, 4(%ecx)
	ret

6f28b87039 Use size_t to store Pos, avoid truncating value 
on 64-bit builds.  Analysis and original patch
by Török Edwin.  Code audit found another place
with the same problem, also fixed here.

cafc567fb7 Finally implement correct ordered comparisons for PPC, even though 
the code generated is not wonderful.  This turns a miscompilation into
a code quality bug (noted in the ppc readme).  This fixes PR642, which
is over 2 years old (!).  Nate, please review this.

of a pointer, since it can never be null.

57e851edfe Rename all the M_* flags to be namespace qualified enums, and switch 
all clients over to using predicates instead of these flags directly.
These are now private values which are only to be used to statically
initialize the tables.
