57c57a3260 Add a new wrapper node for a DILexicalBlock that encapsulates it and a 
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

f8cd4fcba7 N.B. This is with the new EH scheme: 
The blocks with invokes have branches to the dispatch block, because that more
correctly models the behavior of the CFG. The dispatch of course has edges to
the landing pads. Those landing pads could contain invokes, which then have
branches back to the dispatch. This creates a loop. The machine LICM pass looks
at this loop and thinks it can hoist elements out of it. But because the
dispatch is an alternate entry point into the program, the hoisted instructions
won't be executed.

I wasn't able to get a testcase which was small and could reproduce all of the
time. The function_try_block.cpp in llvm-test was where this showed up.

d2cfc2b31f ARM assembly parsing and encoding for LDC{2}{L}/STC{2}{L} instructions. 
Fill out the rest of the encoding information, update to properly mark
the LDC/STC instructions as predicable while the LDC2/STC2 instructions are
not, and adjust the parser accordingly.

fac176ac51 Fix PR11106 by correcting a typo that has been in the code for over a year. This 
would have never worked, since the element type of a vector type is never a
vector type. Also fix the conditional to be more direct in checking whether
EltTy is a vector type.

We parse at least some forms of the instructions now. Encoding is
pretty screwed up, still, though.
