We now produce an identical .o file compared to the cctools
assembler for something like this:

_f0:
L0:
        jmp L1
        .long . - L0
L1:
        jmp A
        .long . - L1

IRgen: Move EmitStoreThroughBitfieldLValue to use new CGBitfieldInfo::AccessInfo decomposition, instead of computing the access policy itself.
 - Sadly, this doesn't seem to give any .ll size win so far. It is possible to make this routine significantly smarter & avoid various shifting, masking, and zext/sext, but I'm not really convinced it is worth it. It is tricky, and this is really instcombine's job.

 - No intended functionality change; the test case is just to increase coverage & serves as a demo file, it worked before this commit.

receiver is a mis-typed class name. Previously, we would give a non-specific
typo-correction diagnostic from the expression-parsing code, but there
was no fix-it because it was too late to recover. Now, we give a nice
diagnostic

honk.m:6:4: error: unknown receiver 'Hnk'; did you mean 'Honk'?
  [Hnk method];
   ^~~
   Honk
honk.m:1:1: note: 'Honk' declared here
@interface Honk
^

which includes a fix-it.

We still need to recover better from mis-typing "super".

here, but it provides a hook so that Sema can typo-correct the
receiver in some cases.

IRgen: Move EmitLoadOfBitfieldLValue to use new CGBitfieldInfo::AccessInfo decomposition, instead of computing the access policy itself.
 - This lets the method focus slightly more on emitting clean IR to honor the policy which has been selected. On 403.gcc's combine.c, x86_64, -O0, this reduces the number of lines in the .ll file (~= # of instructions) by 2.5%.

 - No intended functionality change -- at -O3 this should produce equivalent if not identical output. On 403.gcc's combine.c, x86_64, -O3, this isn't quite true and some of the changes are regressions, but I'm not going to worry about that until we move to a new access policy.

 - There is still some room for improvement in the generated IR, in particular we can usually fold the sign-extension of the bit-field into one of the component access. See the FIXME.

This test relies on iSel lowering dbg_declare intrinsic when CodeGen::OptLevel is None. On PPC side, CodeGen::OptLevel stays to default when -O0 is used on the command line.
