code won't actually get used yet because we don't handle non-type

Comments: Create larger struct fields for consecutive bitfields. (Again).

When creating an LLVM struct type for a struct with bitfields, try to allocate
integer fields that are as large as possible, taking the following bitfields
into account.

For example, this struct:

  struct S {
    int a, b;
    void *c;
    unsigned d : 8;
    unsigned e : 8;
  };

used to be:

  %struct.S = type { i32, i32, i8*, i8, i8 },

but now it becomes:

  %struct.S = type { i32, i32, i8*, i16 }

This makes it easier for the code generator to shuffle register sized bitfield
groups around in fewer registers. It also means that it is harder for SROA to
isolate bit fields as scalars.

The larger struct fields are only produced when they would be properly aligned
and smaller than the natural machine word size.

This strategy is similar to what clang will be doing. We will see how it works
out.Properties:

Comments: introduce a new recoverable error handling API to LLVMContext
and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)
