Refactor places which perform contextual implicit conversions to go through a
common function. The C++1y contextual implicit conversion rules themselves are
not yet implemented, however.
This also fixes a subtle bug where template instantiation context notes were
dropped for diagnostics coming from conversions for integral constant
expressions -- we were implicitly slicing a SemaDiagnosticBuilder into a
DiagnosticBuilder when producing these diagnostics, and losing their context
notes in the process.

Reject continue/break statements within members of local functions nested within
loop and switch statements, by teaching Scope that a function scope never has
a continue/break parent for the purposes of control flow. Remove the hack in
block and lambda expressions which worked around this by pretending that such
expressions were continue/break scopes.
Remove Scope::ControlParent, since it's unused.
In passing, teach default statements to recover properly from a missing ';', and
add a fixit for same to both default and case labels (the latter already
recovered correctly).

Move -Wswitch-enum to -Wswitch
This matches GCC's documented (& actual) behavior. What Clang had implemented
as -Wswitch-enum was actually GCC's -Wswitch behavior. -Wswitch is on by
default (part of -Wall) and warns if a switch-over-enum, without a default
case, covers all enum values.
-Wswitch-enum, on the other hand, does not have the default clause and should
fire even in the presence of a default. This warning is off by default.
With this change the -Wswitch-enum flag is off-by-default in Clang but has no
functionality at the moment. I'll add that in a future commit.

Expand the coverage of the warning for constants on the RHS of logical operands:
return f() || -1;
where the user meant to write '|'.
This bootstraps without any additional warnings.

compute the integer width, not the memory width here. We want to know that
_Bool is 1 bit, not 8. This fixes an assertion on the testcase, which is
PR9304 and rdar://9045501.

turn down the logical bitwise confusion warning to not warn
when the RHS of the ||/&& is ever 0 or 1. This handles a variety of
creative idioms for "true" used in C programs and fixes many false
positives at the expense of a few false negatives. This fixes
rdar://8230351.

Add a warning to catch a bug recently caught by code review, like this:
t2.c:2:12: warning: use of logical && with constant operand; switch to bitwise &
or remove constant [-Wlogical-bitwise-confusion]
return x && 4;
^ ~
wording improvement suggestions are welcome.

If a switch condition is constant, don't warn about missing enum cases.
If a switch condition is constant, warn if there's no case for it.
Constant switch conditions do come up in reasonable template code.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
