[Bug inline-asm/20518] New: Clobber registers,in inline asm. Problem when using rcall

[bl at rosetechnology dot dk]

When register are listet as clobbert, they are used anyway for local variables 
if the inline assembly code uses rcall. The r1 (zeroreg) is not restored even 
if it is clobbert.
None of these problems genrates error or warnings.
