Several changes together in a murky mess:
...
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into
a new static HandlePrefixedOrGroupedOption function.
4. Greatly simplify the implementation of getOptionPred, and make
it avoid splitting prefix options at = when that doesn't match
a non-prefix option.

Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't

working. To support this, add an is_displayed() function to raw_ostream,

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.
While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.

Prune #includes from llvm/Linker.h and llvm/System/Path.h,
...
forcing them down into various .cpp files.
This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
instead.
4. Weans llvm-db off <iostream>
sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

Fix off-by-one in llvm::Format::print.
...
- This also shortens the Format.h implementation, and uses the print buffer
fully (it was wasting a character).
- This manifested as llvm-test failures, because one side effect was that
raw_ostream would write garbage '\x00' values into the output stream if it
happened that the string was at the end of the buffer. This meant that grep
would report 'Binary file matches', which meant the silly pattern matching
llvm-test eventually does would fail. Cute. :)

Other unrelated changes conflated into this patch:
1. REmove EH stuff from llvm-dis and llvm-as, the try blocks
are dead.
2. Simplify the filename inference code in llvm-as/llvm-dis,
because raw_fd_ostream does the right thing with '-'.
3. Switch machine verifier to use raw_ostream instead of ostream
(Which is the thing that needed append in the first place).

Change raw_svector_ostream to reserve the input buffer if necessary, Ted was
...
right.
- This class turns out to be much more convenient to use if we do this; clients
can make sure the buffer is always big enough if they care (since our current
idiom tends to be to use a SmallString<256> for the input to this we should
generally be avoiding an unnecessary malloc).
Also, add a convenience raw_svector_ostream::str method which flushes the buffer
and returns a StringRef for the vector contents.

Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to be

unbuffered. std::ostream does its own buffering, and std::string and
SmallVector both have allocation strategies intended to handle frequent
appending.

Fix FindExecutable to use sys::Path::GetMainExecutable instead of

just argv[0]. And remove the code for searching the current

current executable.

want PATH searching.

Pass target triple string in to TargetMachine constructor.
...
This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.
This has one important change in the way behavior of the JIT and llc.
For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.
For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.
The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.

Twines: Support numeric conversion directly (uitostr, etc).
...
- Provides static constructors for doing number to string conversions without
using temporaries.
- There are several ways to do this, I think given the Twine constraints this
is the simplest one.
- One FIXME for fast number -> hex conversion.
- Added another comment on one last major bit of perf work Twines need, which
is to make raw_svector_ostream more efficient.
