484d3cf0e3 Use getPrimitiveSizeInBits() instead of getPrimitiveSize()*8
Completely rework the 'setcc (cast x to larger), y' code.  This code has
the advantage of implementing setcc.ll:test19 (being more general than
the previous code) and being correct in all cases.

This allows us to unxfail 2004-11-27-SetCCForCastLargerAndConstant.ll,
and close PR454.

18969fbc9f Implement the --enable-targets= feature of the configure script. The make
variable TARGETS_TO_BUILD is used to determine which targets in lib/Target
are built and which libraries are linked into llc. This effectively
implements the feature. One item remains: disabling targets in the dejagnu
test suite.

588bbbffa1 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. :)

        %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.
