[SystemZ] Improve emitSelect()

Merge more Select pseudo instructions in emitSelect() by allowing other
instructions between them as long as they do not clobber CC.

Debug value instructions are now moved down to below the new PHIs instead of
erasing them.

Rename ExpandISelPseudo->FinalizeISel, delay register reservation

This allows targets to make more decisions about reserved registers
after isel. For example, now it should be certain there are calls or
stack objects in the frame or not, which could have been introduced by
legalization.

Describe stack-id as an enum

This patch changes MIR stack-id from an integer to an enum,
and adds printing/parsing support for this in MIR files. The default
stack-id '0' is now renamed to 'default'.

This should make MIR tests that have stack objects with different stack-ids
more descriptive. It also clarifies code operating on StackID.

[SystemZ] Model floating-point control register

This adds the FPC (floating-point control register) as a reserved
physical register and models its use by SystemZ instructions.

Note that only the current rounding modes and the IEEE exception
masks are modeled. *Changes* of the FPC due to exceptions (in
particular the IEEE exception flags and the DXC) are not modeled.

At this point, this patch is mostly NFC, but it will prevent
scheduling of floating-point instructions across SPFC/LFPC etc.

[SystemZ] Handle DBG_VALUE instructions in two places in backend.

Two backend optimizations failed to handle cases when compiled with -g, due
to failing to consider DBG_VALUE instructions. This was in
SystemZTargetLowering::emitSelect() and
SystemZElimCompare::getRegReferences().

This patch makes sure that DBG_VALUEs are recognized so that they do not
affect these optimizations.

Tests for branch-on-count, load-and-trap and consecutive selects.
