Remove an unnecessary predicate.
Patch by Scott Michel.

Review changes:
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
   corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
   converts to bool as comparison against 0. This allows the normal && and
   || operators to be used as if (X.getBoolValue() && Y.getBoolValue())

Note: this still doesn't function 100% yet. I'm working on the bugs now.

There is no circular dependency between llvm and llvm-gcc anymore. stop
scaring users.

Refix CodeGen/Generic/switch-lower.ll.  In contrast to my previous patch,
this doesn't miscompile lots of programs :)

From Dan Gohman:

While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

Generalize TargetData strings, to support more interesting forms of data.
Patch by Scott Michel.

Use brute-force algorithm for to_string. It doesn't have to be efficient
at this point, it just needs to work so we can test things reliably.

sanity check for *basic* i128 arithmetic on all hosts.

better support for i128.

implement expand of truncate.  This allows truncates from i128 to i64 to
be supported on 32-bit hosts.

Fix PR1198, by adding initial i128 support.  Patch by Dan Gohman.
