d69a9cc334 emit integer and fp zeros as (e.g.) .byte 0 instead of .space 1, 
for tidiness.

3104fa4a71 signficant cleanups to EmitGlobalConstant (including streamerization 
of int initializers), change some methods to be static functions,
use raw_ostream::write_hex instead of a smallstring dance with 
APValue::toStringUnsigned(S, 16).

1d3b05933f make mcasmstreamer handle expanding 8 byte integer constants to 
4-byte constants if .quad isn't supported.  Switch a bunch of
methods used by the dwarf writer to use OutStreamer.EmitIntValue.

f25a9e1265 revert 93934, removing the MCAsmInfo endianness bit. I can't 
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

logic enforced in the test case as well, so hopefully it is correct. Please

4ca37472ec When doing address-mode sinking, expand the base register first, rather 
than the scaled register. This makes it more likely that subsequent
AddrModeMatcher queries will match the new address the same way as the
old, instead of accidentally matching what had been the base register
as the new scaled register, and then failing to match the scaled register.
This fixes some problems with address-mode sinking multiple muls into a
block, which will be a lot more common with some upcoming
LoopStrengthReduction changes.

8e3badb9a7 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but 
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.

985ff03e7d Added a Lex function to the AsmParser, to allow handling

7c3ff46d45 add an MCAsmStreamer::EmitFill specialization of EmitFill that

034f69e0aa For aligned load/store instructions, it's only required to know whether a 
function can support dynamic stack realignment. That's a much easier question
to answer at instruction selection stage than whether the function actually
will have dynamic alignment prologue. This allows the removal of the
stack alignment heuristic pass, and improves code quality for cases where
the heuristic would result in dynamic alignment code being generated when
it was not strictly necessary.
