57b6e9eb6c Remove the -enable-sjlj-eh option, which doesn't do anything. 
Remove the -enable-eh option which is only used by the JIT,
and replace it with -jit-enable-eh.

7261fb2a6f Teach X86FloatingPoint that a register can be killed multiple times by the same 
instruction.

This instruction would crash the pass:

  INLINEASM <es:foo $0 $1>, 9, %FP0<kill>, 9, %FP0<kill>, 14, %EFLAGS<earlyclobber,def,dead>

Now it doesn't.

8b1190a540 Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

ee9eb411ff on darwin empty functions need to codegen into something of non-zero length, 
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505
