pseudonym.

Francois Pichet a3037c3abd Always use binary mode for output stream. This is important to prevent unwanted end of line conversion on Windows. Should not affect Unix where O_BINARY is not defined. This fix /clang/test/lexer/preamble.c XFAIL on WIN32.

Jakob Stoklund Olesen f11318018a Only split around a loop if the live range has uses outside the loop periphery. 
Before we would also split around a loop if any peripheral block had multiple
uses. This could cause repeated splitting when splitting a different live range
would insert uses into the periphery.

Now -spiller=inline passes the nightly test suite again.

Owen Anderson afb95571d0 Try again at implementing thread-safe lazy pass initialization, without depending on static local initialization 
being threadsafe AND ensuring that initialization is complete by the time the initializeFooPass method returns.

Owen Anderson a1cc6ec3fb Revert r116489. It included some changes I didn't intend to commit, and broke the buildbots.

Owen Anderson d65924f4a0 Apparently MSVC doesn't support thread-safe static local initialization. Roll our own solution instead.

creates a cyclic dependency that breaks the build when

Bill Wendling 6f52f8a87d Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on 
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.

Chris Lattner 698661c741 add uadd_ov/usub_ov to apint, consolidate constant folding 
logic to use the new APInt methods.  Among other things this
implements rdar://8501501 - llvm.smul.with.overflow.i32 should constant fold

Owen Anderson 6bc4f49f89 Conversely, Analysis-implementations do NOT need to initialize the AnalysisGroup. It will only matter when 
someone tries to require that AG, in which case it is the requester's responsibility to initialize it.

Jim Grosbach efc066829b Make a few more bits of some simple instructions explicit. nop, yield, wfe, 
wfi, sel, sev and bkpt. All would disassemble properly before, but more
explicitness is good, especially with the integrated assembler coming in
the future.
