While I don't yet see a case here to justify making this change generally, it
may be useful to change this for private builds of gcc.  For those cases,
change this line in gcc/genconfig.c:

  max_recog_operands = 29;  /* We will add 1 later.  */

This generates MAX_RECOG_OPERANDS in insn-config.h, which controls the number
of parameters for asm statements.

Like Andrew, I would be interested to see what you are doing that modifies > 15
registers in inline asm on x86.  My gut says there's got to be a cleaner way
than throwing more parameters at it, but maybe not.
