316009054e Add ARM-specific DAG combining to cast i64 vector element load/stores to f64. 
Type legalization splits up i64 values into pairs of i32 values, which leads
to poor quality code when inserting or extracting i64 vector elements.
If the vector element is loaded or stored, it can be treated as an f64 value
and loaded or stored directly from a VPR register.  Use the pre-legalization
DAG combiner to cast those vector elements to f64 types so that the type
legalizer won't mess them up.  Radar 8755338.

f1b4eafbfe rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

6e90ce21cc If we're not using reg+reg offset we're using reg+imm, set the opcode 
to be the one we want to use. bugpoint reduced testcase is a little large,
I'll see if I can simplify it down more.

a519d57725 Fix a copy-pasto. When the tBR_JTr instruction was converted to using the 
tPseudoInst class, its size was changed from "special" to "2 bytes". This is
incorrect because the jump table will no longer be taken into account when
calculating branch offsets.

a68a4fdf37 r120333 changed the opcode for the Thumb1 stuff from ARM::tMOVr to 
ARM::tMOVgpr2gpr. But this check didn't change. As a result, we were getting
misaligned references to the jump table from an ADR instruction.

There is a test case, but unfortunately it's sensitive to random code changes.

976ef86689 During local stack slot allocation, the materializeFrameBaseRegister function 
may be called. If the entry block is empty, the insertion point iterator will be
the "end()" value. Calling ->getParent() on it (among others) causes problems.

Modify materializeFrameBaseRegister to take the machine basic block and insert
the frame base register at the beginning of that block. (It's very similar to
what the code does all ready. The only difference is that it will always insert
at the beginning of the entry block instead of after a previous materialization
of the frame base register. I doubt that that matters here.)
