9ea3f56d07 Teach isGAPlusOffset to respect a GlobalAddressSDNode's offset 
value, which is something that apparently isn't used much.

7dc1def162 Re-apply 52002, allowing the verifier to accept non-MRV struct return 
types on functions, with adjustments so that it accepts both
new-style aggregate returns and old-style MRV returns, including those
with only a single member.

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.

83ec4b6711 Wrap MVT::ValueType in a struct to get type safety 
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).
