Add low-level option for avoiding float stores from va_start until
soft-float is properly supported.

Added a TLI hook to signal that the target does not have or does not care about
floating point exceptions, added use of flag to fold potentially exception 
raising floating point math in selection DAG. No functionality change, as 
targets have to explicitly ask for this behavior and none does today.

I supposed PRIx32 might be unused in the tree.

DebugInfo: Recommit (reverted in r215217, originally committed in r215157) the assertion that no argument variable is overwritten by subsequent argument variables.

This turned up a bug in clang where arguments were emitted with
duplicate argument numbers (see r215227).

[FastISel][X86] Use INC/DEC when possible for {sadd|ssub}.with.overflow intrinsics.

This is a small peephole optimization to emit INC/DEC when possible.

AArch64: avoid deleting the current iterator in a loop.

std::map invalidates the iterator to any element that gets deleted, which means
we can't increment it correctly afterwards. This was causing Darwin test
failures.

[FastISel][X86] Fix INC/DEC optimization (r215230)

I accidentally also used INC/DEC for unsigned arithmetic which doesn't work,
because INC/DEC don't set the required flag which is used for the overflow
check.

[MCJIT] Simplify immediate decoding code in the RuntimeDyldMachO hierarchy.

Cleanup only: no functional change.

This patch makes RuntimeDyldMachO targets directly responsible for decoding
immediates, rather than letting them implement catch a callback from generic
code. Since this is a very target specific operation, it makes sense to let the
target-specific code drive it.
