commit 8a85f9f29f13805af449943990af8af8399ab7b5
Author: Stephan Bergmann <sbergman at redhat.com>

    Drop unnecessary nFPR parameter
    
    ...as passing (an upper bound on) the number of vector registers used in %al is
    only required for variable-argument function calls, according to
    <http://www.x86-64.org/documentation/abi.pdf> "System V Application Binary
    Interface: AMD64 Architecture Processor Supplement, Draft Version 0.99.6."
    
    Unclear why this got added in f424e55b4e66ffbee5b34f45ef5ea18d77c4d15c
    "INTEGRATION: CWS sixtyfour11," maybe on the basis of "doesn't hurt."
