b2888f6712 Add the RUN: prefix to the start of the run line so this test doesn't fail. 
BTW .. isn't the date on this funky? We haven't reachec 2005-05-09 yet???

f6e98c8cf5 Change some old-style casts to C++ style casts to avoid warnings in XPS 
compilation. This change has been waiting in the wings for a long time but
since Misha just did a global change, I figured now was the time to commit
it.

8d813a7d51 Handle stores of global address as stores of immediates. Instead of: 
test1:
        movl $N, %eax
        movl %eax, G
        ret

emit:

test1:
        movl $N, G
        ret

706775467b Handle (store &GV -> mem) as a store immediate. This often occurs for 
printf format strings and other stuff.  Instead of generating this:

        movl $l1__2E_str_1, %eax
        movl %eax, (%esp)

we now emit:

        movl $l1__2E_str_1, (%esp)

87fbc1c554 Improve and elimination. On PPC, for: 
bool %test(int %X) {
        %Y = and int %X, 8
        %Z = setne int %Y, 0
        ret bool %Z
}

we now generate this:

        rlwinm r2, r3, 0, 28, 28
        srwi r3, r2, 3

instead of this:

        rlwinm r2, r3, 0, 28, 28
        srwi r2, r2, 3
        rlwinm r3, r2, 0, 31, 31

I'll leave it to Nate to get it down to one instruction. :)

d0a2fda2c6 Fold (x & 8) != 0 and (x & 8) == 8 into (x & 8) >> 3. 
This turns this PPC code:

        rlwinm r2, r3, 0, 28, 28
        cmpwi cr7, r2, 8
        mfcr r2
        rlwinm r3, r2, 31, 31, 31

into this:

        rlwinm r2, r3, 0, 28, 28
        srwi r2, r2, 3
        rlwinm r3, r2, 0, 31, 31

Next up, nuking the extra and.

5ad1e1ebec Instcombine this: 
%shortcirc_val = select bool %tmp.1, bool true, bool %tmp.4             ; <bool> [#uses=1]
        %tmp.6 = cast bool %shortcirc_val to int                ; <int> [#uses=1]

into this:

        %shortcirc_val = or bool %tmp.1, %tmp.4         ; <bool> [#uses=1]
        %tmp.6 = cast bool %shortcirc_val to int                ; <int> [#uses=1]

not this:

        %tmp.4.cast = cast bool %tmp.4 to int           ; <int> [#uses=1]

6ce1b109aa Teach simplifycfg that setcc is cheap and non-trapping, so that it can 
convert this:

        %tmp.1 = seteq int %i, 0                ; <bool> [#uses=1]
        br bool %tmp.1, label %shortcirc_done, label %shortcirc_next

shortcirc_next:         ; preds = %entry
        %tmp.4 = seteq int %j, 0                ; <bool> [#uses=1]
        br label %shortcirc_done

shortcirc_done:         ; preds = %shortcirc_next, %entry
        %shortcirc_val = phi bool [ %tmp.4, %shortcirc_next ], [ true, %entry ]         ; <bool> [#uses=1]

to this:
        %tmp.1 = seteq int %i, 0                ; <bool> [#uses=1]
        %tmp.4 = seteq int %j, 0                ; <bool> [#uses=1]
        %shortcirc_val = select bool %tmp.1, bool true, bool %tmp.4             ; <bool> [#uses=1]

... which is later simplified by instcombine into an or.

Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.
