[Bug c/41045] New: Extended asm with C operands doesn’t work at top level

[anders at kaseorg dot com]

IÂ’d like to be able to write toplevel inline assembly with C operands that are
compile-time constants, e.g.

static const char foo[] = "Hello, world!";
enum { bar = 17 };
asm(".pushsection baz; .long %c0, %c1, %c2; .popsection"
    : : "i" (foo), "i" (sizeof(foo)), "i" (bar));

However, this currently fails with “error: expected ‘)’ before ‘:’ token” at
the top level, even though it works fine inside a function.
