This introduces a threshold of 200 IV Users, which is very
conservative but should be sufficient to avoid serious compile time
sink or stack overflow. The llvm test-suite with LTO never exceeds 190
users per loop.
The bug doesn't relate to a specific type of loop. Checking in an
arbitrary giant loop as a unit test would be silly.
Fixes rdar://11262507.

Follow up to r154924: check that we are in a static CMethodDecl to enable the Microsoft bug emulation regarding access to protected member during PTM creation. Not just any static function.

Unprintable source in diagnostics is transformed to a printable form and then
displayed with reversed colors if possible. Unprintable characters are
displayed as <U+NNNN> while bytes that do not represent valid characters are
shown as <XX>.
Column adjustments to diagnostic carets, highlighted ranges, and fixups are
made both for characters escaped as above and for characters which are
printable but take up more than a single column.

Also enabled PlatformRemoteiOS to select an SDK using the build number in case you have mutliple 5.0 SDKs installed:
(lldb) platform select remote-ios --build 11C123

transformation:
(X op C1) ^ C2 --> (X op C1) & ~C2 iff (C1&C2) == C2
should be done.
This change has been tested:
Using a debug+asserts build:

using this clang to build a release version of clang
Using the release+asserts clang-with-clang build:

Checking in because Evan wants it checked in. Test case forthcoming after
scrubbing.

This will allow us to delete the JSON parser from llvm.
The biggest change is a general change of strategy - instead
of storing StringRef's to the values for the command line and
directory in the input buffer, we store ScalarNode*'s. The
reason is that the YAML parser's getRawValue on ScalarNodes
returns a string that includes the quotes in case of double
quoted strings.
For the same reason we're removing the JSON parsing part of
the command line parsing - this means an extra copy for a
command line when it is requested (and only when it is requested).

for the life of me remember why I wrote it this way, but I can't see any good
reason for it now. This patch replaces the custom linked list with an ilist.
This change should preserve the existing numberings exactly, so no generated code
should change (if it does, file a bug!).
