[PATCH] Support default integer attribute arguments

[Aaron Ballman]

Attr.td has the notion of a DefaultIntArgument that currently does
nothing special. This patch adds table generator support such that
attributes which use the DefaultIntArgument type are given a static
const class member that names the default value.  Eg)

let Args = [DefaultIntArgument<"Priority", 65535>];

Would give the generated attribute class a public member:

static const int DefaultPriority = 65535;

This can then be used in place of magic numbers elsewhere (and
consequently, this patch removes a few such FIXMEs).
