input such as test.c to named temporary would be something like test-3O4Clq.o

after having already deserialized the fields, clear out the fields
first. This makes sure that we keep all of the declarations in the
lexical context (including those implicitly added by later
type-checking) within the same list. A test case for this behavior is
coming as part of another commit; testing for this problem in
isolation is a nightmare.

invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons.  We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts.  Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits.  This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

I don't really like the patterns, but I'm having trouble coming up with a
better way to handle them.

I plan on making other targets use the same legalization
ARM-without-memory-barriers is using... it's not especially efficient, but
if anyone cares, it's not that hard to fix for a given target if there's
some better lowering.

SimplifyCFG: If we have a PHI node that can evaluate to NULL and do a load or store to the address returned by the PHI node then we can consider this incoming value as dead and remove the edge pointing there, unless there are instructions that can affect control flow executed in between.

In theory this could be extended to other instructions, eg. division by zero, but it's likely that it will "miscompile" some code because people depend on div by zero not trapping. NULL pointer dereference usually leads to a crash so we should be on the safe side.

This shrinks the size of a Release clang by 16k on x86_64.
