Description

[WebAssembly] Move .debug_line section address of dead function outside section range

Summary:
Currently we are pointing all debug information that refer removed function code
to the beginning of the code section (offset = 0). A debugger may want to
resolve code offset to the debug information, which will collide with offsets
of the live functions.

Moving offsets of dead functions outside code section range.
