    Scan inlinable methods for references to global variables and
    functions (forgot to do that earlier).
    
    Track all packages mentioned by exports (that should have been done
    earlier too).
    
    Record assembler name in export data, so that we can inline calls to
    non-Go functions.  Modify gccgoimporter code to skip assembler name.
    
    This increases the number of inlinable functions in the standard
    library from 215 to 439.

    When converting a constant to interface, such as interface{}(42)
    or interface{}("hello"), if the interface escapes, we currently
    generate a heap allocation to hold the constant value.
    
    This CL changes it to generate a static allocation instead, as
    the gc compiler does. This reduces allocations in such cases.
