Adjust the heuristics used to decide when SROA is likely to be profitable.
The SRThreshold value makes perfect sense for checking if an entire aggregate
should be promoted to a scalar integer, but it is not so good for splitting
an aggregate into its separate elements.  A struct may contain a large embedded
array along with some scalar fields that would benefit from being split apart
by SROA.  Even if the total aggregate size is large, it may still be good to
perform SROA.  Thus, the most important piece of this patch is simply moving
the aggregate size comparison vs. SRThreshold so that it guards only the
aggregate promotion.

We have also been checking the number of elements to decide if an aggregate
should be split up.  The limit of "SRThreshold/4" seemed rather arbitrary,
and I don't think it's very useful to derive this limit from SRThreshold
anyway.  I've collected some data showing that the current default limit of
32 (since SRThreshold defaults to 128) is a reasonable cutoff for struct
types.  One thing suggested by the data is that distinguishing between structs
and arrays might be useful.  There are (obviously) a lot more large arrays
than large structs (as measured by the number of elements and not the total
size -- a large array inside a struct still counts as a single element given
the way we do SROA right now).  Out of 8377 arrays where we successfully
performed SROA while compiling a large set of benchmarks, only 16 of them had
more than 8 elements.  And, for those 16 arrays, it's not at all clear that
SROA was actually beneficial.  So, to offset the compile time cost of
investigating more large structs for SROA, the patch lowers the limit on array
elements to 8.

This fixes Apple Radar 7563690.

remove the # TAILCALL markers, which was causing the to fail.
It's unclear if the matcher is nondeterminstic of what here,
but I'm getting matches without TAILCALL and some other hosts
are getting matches with it.

Remove a bunch of stuff around the edges of the ELF writer.
Now the only use of the ELF writer is the JIT, which won't be
easy to fix in the short term. :( :(

eliminate FileModel::Model, just use CodeGenFileType.  The client

Renamed the ed directory to edis, as suggested
yesterday.  This eliminates possible confusion
about what exactly in this directory; the name
is still short, though.

eliminate all forms of addPassesToEmitMachineCode except
the one used by the JIT.  Remove all forms of

addPassesToEmitFileFinish into its only caller.

Added another version of the X86 assembler matcher test case.
This test case is different subset of the full auto generated test case, and a
larger subset that is in x86_32-bit.s (that set will encode correctly).  These
instructions can pass though llvm-mc as it were a logical cat(1) and then
reassemble to the same instruction.  It is useful as we bring up the parser and
matcher so we don't break things that currently work.

Test revert 95050; there's a good chance it's causing
