Generalize DebugInfo tests by avoiding explicit metadata numbers

numbers. Wherever the same number appeared more than once in a test I used
a named match to ensure the same number appeared in all those cases (this may
still be overly constraining test cases as they may not have actually cared
about that relationship). For one-off numbers I just replaced them with an
unnamed regex.

This may underconstrain poorly written test cases that were interested in
checking that certain metadata nodes were related but didn't actually match
on all the related nodes numbers.

Fix PR14881 by implementing conversion rules between int and complex int.

Prior to the patch, Clang does not properly promote types when a complex
integer operand is combined with an integer via a binary operator, or when
one is assigned to the other in either order.  This patch detects when
promotion is needed (and permissible) and generates the necessary code.

The test assmes no target has the same size operands for "char" and
"long long," and that no target performs arithmetic on char operands without
extending them to a larger format first.  If there are any targets for
which this is not the case, they should be XFAILed.

Re-design the convenience interfaces on MatchFinder.

First, this implements a match() method on MatchFinder; this allows us
to get rid of the findAll implementation, as findAll is really a special
case of recursive matchers on match.

Instead of findAll, provide a convenience function match() that lets
users iterate easily over the results instead of needing to implement
callbacks.

Revamp of the basic layouting algorithm in clang-format.

In order to end up with good solutions, clang-format needs to try
"all" combinations of line breaks, evaluate them and select the
best one. Before, we have done this using a DFS with memoization
and cut-off conditions. However, this approach is very limited
as shown by the huge static initializer in the attachment of
llvm.org/PR14959.

Instead, this new implementation uses a variant of Dijkstra's
algorithm to do a prioritized BFS over the solution space.

Some numbers:
lib/Format/TokenAnnotator.cpp: 1.5s -> 0.15s
Attachment of PR14959: 10min+ (didn't finish) -> 10s

No functional changes intended.
