This doesn't change the interface or gives additional safety but removes
a ton of retain/release boilerplate.
No functionality change.

BitstreamWriter asserts that when blob data is written from the record
element vector, each element fits in a byte. However, if the record
elements are specified as a SmallVector of 'char', this causes a warning
from -Wtautological-constant-out-of-range-compare. Fix this by using
llvm::isUInt<8> instead of a plain comparison against 256.

AKA: Recompile *ALL* the source code!
This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

- Widespread trailing space removal
- A dash of OCD spacing to block align enums
- joined a line that probably needed 80 cols a while back

number of bits was bigger than 32. I checked every use of this function
that I could find and it looks like the maximum number of bits is 32, so I've
added an assertion checking this property, and a type cast to (hopefully) stop
PVS-Studio from warning about this in the future.

std::vector.
- Good for 1-2% speedup on writing PCH for Cocoa.h.
- Clang side API match to follow shortly, there wasn't an easy way to make this
non-breaking.

elements in a form that is efficient for the reader to just get a
pointer in memory and start reading. APIs to do efficient reading
and writing are still todo.

bc files for modules with a target triple that indicates they are for
darwin. The reader unconditionally handles this, and the writer could
turn this on for more targets if we care.
This change has two benefits for darwin:
1) it allows us to encode the cpu type of the file in an easy to read
place that doesn't require decoding the bc file.
2) it works around a bug (IMO) in darwin's AR where it is incapable of
handling files that are not a multiple of 8 bytes long. BC files
are only guaranteed to be multiples of 4 bytes long.

relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.
