d07a2eb806 Rename ASSERT* to DCHECK*. 
This way we don't clash with the ASSERT* macros
defined by GoogleTest, and we are one step closer
to being able to replace our homegrown base/ with
base/ from Chrome.

56a486c322 Use full include paths everywhere 
- this avoids using relative include paths which are forbidden by the style guide
- makes the code more readable since it's clear which header is meant
- allows for starting to use checkdeps

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

ad23017469 When strings can change from an ASCII representation to a 
UC16 representation we need to be careful about flat strings.
Flat strings can be sliced or cons strings that have a flat
string under them, so when we ask a flat cons or a slice whether
it is ASCII or not we should ask the underlying string about
its representation.  This should fix

ba09ec5e89 Irregexp: 
* Facility for generating a node several ways.  This allows
  code to be generated for a node knowing where it is trying
  to match relative to the 'current position' and it allows
  code to be generated that knows where to backtrack to.  Both
  allow dramatic reductions in the amount of popping and pushing
  on the stack and the number of indirect jumps.
* Generate special backtracking for greedy quantifiers on
  constant-length atoms.  This allows .* to run in constant
  space relative to input string size.
* When we are checking a long sequence of characters or character
  classes in the input then we do them right to left and only the
  first (rightmost) needs to check for end-of-string.
* Record the pattern in the profile instead of just <CompiledRegExp>
* Nodes no longer contain an on_failure_ node.  This was only used
  for lookaheads and they are now handled with a choice node instead.
