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.

This is a follow up of r325012, that allowed half types in constant pools.
Proper alignment was enforced when a big basic block was split up, but not when
a CPE was placed before/after a block; the successor block had the wrong
alignment.

Change ARMConstantIslandPass to:
- accept f16 literals as litpool entries,
- if the litpool needs to be inserted in the middle of a big block, then we
need to 4-byte align the next instruction in ARM mode.
