Duraid Madina e977a93bd5 support functions that return bool (this "should" work but doesn't, 
*maybe* due to a legalizer bug.)

Reid Spencer 5995c57574 For PR521: 
With these patches we implement the ability for the Linker library to
keep track of which libraries were actually bytecode files (not archives)
and cause their users to remove such files from the list of libraries to
pass to the native linker.

Evan Cheng 4b0623e141 * Remove instruction fields hasInFlag / hasOutFlag and added SNDPInFlag and

optional. Used by ret / call, etc.

Chris Lattner eb372a0276 Enhance the shift-shift folding code to allow a no-op cast to occur in between 
the shifts.

This allows us to fold this (which is the 'integer add a constant' sequence
from cozmic's scheme compmiler):

int %x(uint %anf-temporary776) {
        %anf-temporary777 = shr uint %anf-temporary776, ubyte 1
        %anf-temporary800 = cast uint %anf-temporary777 to int
        %anf-temporary804 = shl int %anf-temporary800, ubyte 1
        %anf-temporary805 = add int %anf-temporary804, -2
        %anf-temporary806 = or int %anf-temporary805, 1
        ret int %anf-temporary806
}

into this:

int %x(uint %anf-temporary776) {
        %anf-temporary776 = cast uint %anf-temporary776 to int
        %anf-temporary776.mask1 = add int %anf-temporary776, -2
        %anf-temporary805 = or int %anf-temporary776.mask1, 1
        ret int %anf-temporary805
}

note that instcombine already knew how to eliminate the AND that the two
shifts fold into.  This is tested by InstCombine/shift.ll:test26
