8eab8a2798 Remove some DAG combiner assumptions about sizes 
of integer types.  Fix the isMask APInt method to
actually work (hopefully) rather than crashing
because it adds apints of different bitwidths.
It looks like isShiftedMask is also broken, but
I'm leaving that one to the APInt people (it is
not used anywhere).

822143e6f7 use 'continue' to make the function linker simpler. When linking a strong 
function into a weak function, zap the weak function body so that the
strong one overrides it.  This fixes PR2410

8e4eb09b1e Remove comparison methods for MVT. The main cause 
of apint codegen failure is the DAG combiner doing
the wrong thing because it was comparing MVT's using
< rather than comparing the number of bits.  Removing
the < method makes this mistake impossible to commit.
Instead, add helper methods for comparing bits and use
them.
