Jakob Stoklund Olesen 89bd2ae517 Remove an assertion to fix PR9872. 
It can happen that a live debug variable is the last use of a sub-register, and
the register allocator will pick a larger register class for the virtual
register.  If the allocated register doesn't support the sub-register index,
just use %noreg for the debug variables instead of asserting.

In PR9872, a debug variable ends up in the sub_8bit_hi part of a GR32_ABCD
register. The register is split and one part is inflated to GR32 and assigned
%ESI because there are no more normal uses of sub_8bit_hi.

Since %ESI doesn't have that sub-register, substPhysReg asserted. Now it will
simply insert a %noreg instead, and the debug variable will be marked
unavailable in that range.

We don't currently have a way of saying: !"value" is in bits 8-15 of %ESI, I
don't know if DWARF even supports that.

Benjamin Kramer d724a590e5 X86: Add a bunch of peeps for add and sub of SETB. 
"b + ((a < b) ? 1 : 0)" compiles into
	cmpl	%esi, %edi
	adcl	$0, %esi
instead of
	cmpl	%esi, %edi
	sbbl	%eax, %eax
	andl	$1, %eax
	addl	%esi, %eax

This saves a register, a false dependency on %eax
(Intel's CPUs still don't ignore it) and it's shorter.

Duncan Sands af32728a57 The comparision "max(x,y)==x" is equivalent to "x>=y". Since the max is 
often expressed as "x >= y ? x : y", there is a good chance we can extract
the existing "x >= y" from it and use that as a replacement for "max(x,y)==x".

Jakob Stoklund Olesen a5c889982a Emit a proper error message when register allocators run out of registers. 
This can't be just an assertion, users can always write impossible inline

Nick Lewycky 64c9284411 It's valid to take the blockaddress of a different function, so remove this 
assert in the bitcode writer. No change needed because the ValueEnumerator holds
a whole-module numbering anyhow. Fixes PR9857!

Jakob Stoklund Olesen f8da028895 Update LiveDebugVariables after live range splitting. 
After a virtual register is split, update any debug user variables that resided
in the old register. This ensures that the LiveDebugVariables are still correct
after register allocation.

This may create DBG_VALUE instructions that place a user variable in a register
in parts of the function and in a stack slot in other parts. DwarfDebug
currently doesn't support that.

Andrew Trick aab77fe574 Post-RA scheduler compile time fix. Quadratic computation of DAG node depth. 
The post-ra scheduler was explicitly updating the depth of a node's
successors after scheduling it, regardless of whether the successor
was ready. This is quadratic for DAGs with transitively redundant
edges. I simply removed the useless update of depth, which is lazilly
computed later.
Fixes <rdar://problem/9044332> compiler takes way too long to build TextInput.
