LOG: [InlineSpiller] Fix missing LiveRegMatrix declaration. NFC.

b25b51eb639d adds a reference to LiveRegMatrix in Spiller.h without
including the header, or adding a declaration.  That breaks modules
builds.

It looks like it might get reverted in #137801, but let's fix the
breakage in the meantime.
