The inline asm operand modifier 'n' is suppose

to be generic across architectures. It has the
following description in the gnu sources:

    Negate the immediate constant

Several Architectures such as x86 have local implementations
of operand modifier 'n' which go beyond the above description
slightly. This won't affect them.

Affected files:

    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'n' to the switch cases.

    test/CodeGen/Generic/asm-large-immediate.ll
        Generic compiled test (x86 for me)

    test/CodeGen/Mips/asm-large-immediate.ll
        Mips compiled version of the generic one
