Jeremy Morse 6df259fb43 [InstrRef][X86] Drop debug instruction numbers from x87 instructions 
Avoid a crash when using instruction referencing if x87 floating point
instructions are used. These instructions are significantly mutated when
they're rewritten from referring to registers, to referring to
floating-point-stack positions. As a result, their operands are re-ordered,
and (InstrRef) LiveDebugValues asserts when it sees a DBG_INSTR_REF
referring to a non-reg non-def register operand.

To fix this, drop the instruction numbers, and thus variable locations.
This patch adds a helper utility do do that.

Dropping the variable locations is sub-optimal, but applying DBG_VALUEs to
the $fp0 and similar registers is dropped on emission too. It seems we've
never done well at describing variables that live in x87 registers, at all.
