David Majnemer cc6313da83 [CodeView] Mark our lines as statements, not expressions
The line tables for CodeView make a distinction between expressions and
statements.  As it turns out, MSVC always emits them as statements and
we always emit them as expressions.  Let's switch to statements to match
the CodeView that they emit.

; The bar function happens to have no lexical scopes, yet it has one instruction
; with debug information available. This used to be PR19239.
