[PBQP Regalloc] Pre-spill vregs that have no legal physregs.
The PBQP::RegAlloc::MatrixMetadata class assumes that matrices have at least two

IR: Allow GenericDebugNode construction from MDString
Allow `GenericDebugNode` construction directly from `MDString`, rather
than requiring `StringRef`s. I've refactored the `StringRef`
constructors to use these. There's no real functionality change here,
except for exposing the lower-level API.
The purpose of this is to simplify construction of string operands when
reading bitcode. It's unnecessarily indirect to parse an `MDString` ID,
lookup the `MDString` in the bitcode reader list, get the `StringRef`
out of that, and then have `GenericDebugNode::getImpl()` use
`MDString::get()` to acquire the original `MDString`. Instead, this
allows the bitcode reader to directly pass in the `MDString`.

we can treat r2 as an ordinary callee-saved register (it must be callee-saved

LLVMTargetMachine -- that layer hadn't switched over yet.
The only use of the TargetMachine was to re-lookup a subtarget for
a particular function to work around the fact that TTI was immutable.
Now that it is per-function and we haved a cached subtarget, use it.
This still leaves a few interfaces with real warts on them where we were
passing Function objects through the TTI interface. I'll remove these
and clean their usage up in subsequent commits now that this isn't
necessary.

[multiversion] Remove the cached TargetMachine pointer from the
intermediate TTI implementation template and instead query up to the
derived class for both the TargetMachine and the TargetLowering.
Most of the derived types had a TLI cached already and there is no need
to store a less precisely typed target machine pointer.
This will in turn make it much cleaner to look up the TLI via
a per-function subtarget instead of the generic subtarget, and it will
pave the way toward pulling the subtarget used for unroll preferences
into the same form once we are *always* using the function to look up
the correct subtarget.

[multiversion] Remove another place we were "handling" nullptr even
though it was never a reasonable input.
