[Bug inline-asm/39847] New: 16 symbolic register names generates error: more than 30 operands in 'asm'

[d at teklibre dot com]

Using more than 15 operands in inline assembly of the symbolic form:

  "... lots of assembly elided ..." \
  "movaps %[inner_filter_index], %[icoeff_l2]\n\t"                      \
  :[icoeff_l2] "+x" (icoeff_l2),                                        \
   [inner_filter_index] "+x" (inner_filter_index),                      \
   ... 13 more operands .. .

blows up at 16 register names, which is a bit lower than 30, and in either
case, too low for modern vector architectures such as the x86_64, vmx,
larrabee, etc. 

Test program to come...
