Jakob Stoklund Olesen e3084895d2 Revert r152202: "Use uint16_t to store InstrNameIndices in MCInstrInfo."
We cannot limit the concatenated instruction names to 64K.  ARM is
already at 32K, and it is easy to imagine a target with more
instructions.

Jakob Stoklund Olesen e99d26c68b Revert r152105: "Use uint16_t to store indices into string table"
This patch limited the concatenated register names to 64K which meant
that the total number of registers was many times less than 64K.

If any compilers actually enforce the 64K limit on string literals, and
it turns out to be a problem, we should fix that problem by not using
long string literals.

Greg Clayton 0c94313d20 <rdar://problem/11052829>
Fixed a case where if you have a argument stirng that ends with a '\' character, it would infinite loop while consuming all of your memory.

Also fixed a case where non-quote terminated strings would inefficiently be handled.

The functions memccpy, strdup, strndup, strlcat, and strlcpy should also have
object size checking support. Of course, this is only good if the C library also
supports these functions.

These APIs aren't thread safe, but they're pretending to be. Let's at
least make the getter as fast as they can be. The setters are a lost

David Blaikie aeef2ae8f9 Unpluralize -Wfoo-conversions warnings for consistency.
Err on the side of brevity and rename (while providing aliases for the original
name) -Wbool-conversions, -Wint-conversions, and -Wvector-conversions for
consistency with constant, literal, string, and sign conversion warnings. And
name the diagnostic groups explicitly while I'm here rather than rewriting the
string in the groups and sema td files.

Curiously, vector-conversion is not under -Wconversion. Perhaps it should be.

Richard Smith ce1ec5e1f5 Unrevert r152761 (reverted in r152772) with a fix for the issue which was
breaking bootstrap. No test yet: it's quite hard to tickle the failure case.
The specific testcase for this wouldn't be useful for testing anything more
general than a reintroduction of this precise bug in any case.

David Blaikie ebcbe4b6aa Reapply r152745 (reverted in 152765) now that compiler-rt is fixed.
Original commit message:

Provide -Wnull-conversion separately from -Wconversion.

Like GCC, provide a NULL conversion to non-pointer conversion as a separate
flag, on by default. GCC's flag is "conversion-null" which we provide for
cross compatibility, but in the interests of consistency (with
-Wint-conversion, -Wbool-conversion, etc) the canonical Clang flag is called
-Wnull-conversion.

Patch by Lubos Lunak.
Review feedback by myself, Chandler Carruth, and Chad Rosier.

Sean Callanan cf12862a9a Strengthened LLDB's completion of object types.
Now when LLDB reports a variable, it has a
complete type.  Similarly, when it reports
members of a struct, it completes their types.
Also, when it creates the result variable for
an expression, it ensures that variable's type
is complete.

This ensures compliance with Clang's
expectations, preventing potential crashes.

Richard Smith 79aa513231 Minor optimization to constant evaluation: don't bother computing expr source
locations for diagnostics we're not going to emit, and don't track the subobject
designator outside C++11 (since we're not going to use it anyway).

This seems to give about a 0.5% speedup on 403.gcc/combine.c, but the results
were sufficiently noisy that I can't reject the null hypothesis.
