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

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

    Substitute immediate value without immediate syntax

Several Architectures such as x86 have local implementations
of operand modifier 'c' which go beyond the above description
slightly. To make use of the generic modifiers without overriding
local implementation one can make a call to the base class method
for AsmPrinter::PrintAsmOperand() in the locally derived method's 
"default" case in the switch statement. That way if it is already
defined locally the generic version will never get called.

This change is needed when test/CodeGen/generic/asm-large-immediate.ll
failed on a native Mips board. The test was assuming a generic
implementation was in place.

Affected files:

    lib/Target/Mips/MipsAsmPrinter.cpp:
        Changed the default case to call the base method.
    lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp
        Added 'c' to the switch cases.
    test/CodeGen/Mips/asm-large-immediate.ll

No functional change intended.

Sorry for the churn. The iterator classes are supposed to help avoid
giant commits like this one in the future. The TableGen-produced
register lists are getting quite large, and it may be necessary to
change the table representation.

This makes it possible to do so without changing all clients (again).

DIE for the declaration.  Without this change, if this causes
getOrCreateSubprogramDIE to be recursively called on the definition,
it will create multiple DIEs for that definition.  Fixes PR12831.

Use a dedicated MachO load command to annotate data-in-code regions.
This is the same format the linker produces for final executable images,
allowing consistency of representation and use of introspection tools
for both object and executable files.

Data-in-code regions are annotated via ".data_region"/".end_data_region"
directive pairs, with an optional region type.

data_region_directive := ".data_region" { region_type }
region_type := "jt8" | "jt16" | "jt32" | "jta32"
end_data_region_directive := ".end_data_region"

The previous handling of ARM-style "$d.*" labels was broken and has
been removed. Specifically, it didn't handle ARM vs. Thumb mode when
marking the end of the section.

expression. For instance, we could have an MCExpr like this:

    0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64)

The MCExpr printer handles sizes up to 64-bits, but this expression would
require 128-bits. In this situation, try to evaluate the constant expression and
emit that as the value into 64-bit chunks.
