922ad78776 Make sure we emit the 'movw' and 'movt' only if it's supported. Otherwise, use a constant pool.

a5871dc104 For Thumb mode, we need to use a constant pool if the value is too large to be
used with the CMP instruction.

85f3a0a4c4 Use the integer compare when the value is small enough. Use the "move into a
register and then compare against that" method when it's too large. We have to
move the value into the register in the "movw, movt" pair of instructions.

f7b0207f1e A landing pad could have more than one predecessor. In that case, we want that
predecessor to remove the jump to it as well. Delay clearing the 'landing pad'
flag until after the jumps have been removed. (There is an implicit assumption
in several modules that an MBB which jumps to a landing pad has only two
successors.)

13a7121858 Now Igor, throw the switch...give my creation life!
Use the custom inserter for the ARM setjmp intrinsics. Instead of creating the
SjLj dispatch table in IR, where it frequently violates serveral assumptions --
in particular assumptions made by the landingpad instruction about what can
branch to a landing pad and what cannot. Performing this in the back-end allows
us to violate these assumptions without the IR getting angry at us.

It also allows us to perform a small optimization. We can shove the address of
the dispatch's basic block into the function context and not have to add code
around the setjmp to check for the return value and jump to the dispatch.

Neat, huh?

534849687c Mark tADDrSPi as having side effects again.
It really doesn't, but when r141929 removed the hasSideEffects flag from
this instruction, it caused miscompilations.  I am guessing that it got
moved across a stack pointer update.

Also clear isRematerializable after checking that this instruction is
in fact never rematerialized in the nightly test suite.

d73462a1c9 Thumb1 does not support dynamic stack realignment.
rdar://10288916 is tracking this fix.

In the past, instcombine and other passes were promoting alloca alignment past
the natural alignment, resulting in dynamic stack realignment.  Lang's work now
prevents this from happening (LLVM commit r141599).  Now that this really 
shouldn't happen report a fatal error rather than silently generate bad code.
