Fix the representation of wide strings in the AST and IR so that it uses the native representation of integers for the elements.  This fixes a bunch of nastiness involving
treating wide strings as a series of bytes.

Patch by Seth Cantrell.

llvm-svn: 143417

Perform proper conversion for strings encoded in the source file as UTF-8.  (For now, we are assuming the source character set is always UTF-8; this can be easily extended if necessary.)

Tests will be coming up in a subsequent commit.

This patch ensures that no passes are deleted from clang, such that the loading
of plugins does not fail because of passes being unavailable.  This increases
the size of the clang binary from 43029853 to 43915291 bytes (around 2%).

that it retains source location information for the type. Aside from
general goodness (being able to walk the types described in that
information), we now have a proper representation for dependent
delegating constructors. Fixes PR10457 (for real).

[libclang] Tweak internals of CXSourceLocation to allow an alternate implementation if the lowest bit of ptr_data[0] is not 0.  This
is prep for work on serialized diagnostics.

[libclang] Move implementation of functions for manipulation CXSourceLocations and CXSourceRanges into a separate file.

[libclang] Add CXDiagnosticImpl to represent a super class for the implementation backing a CXDiagnostic.  This allows CXStoredDiagnostic
to be just one possible implementation of a CXDiagnostic.

because we don't want to take this performance hit when doing code completion

Log of r143342:
Move caching of code-completion results from ASTUnit::Reparse to ASTUnit::CodeComplete,
so that it will happen when we are doing code-completion, not reparsing.

In x86_64, when calling an Objective-C method that returns a _Complex long double, make sure to use the objc_msgSend_fp2ret function which ensures that the return value will be {0, 0} if the receiver is nil.

I don't have any Debian system with one of these currently, and it seems
unlikely for one to show up suddenly. We can add more patterns here if
they become necessary.

search logic. The Debian multiarch seems to have completely changed from
when these were originally added, and I'd like to remove a bunch of
them, but I'll be lazy and delay that until this logic is hoisted into
the driver where it belongs.

This should resolve PR11223.

llvm-svn: 143345

library search logic to "properly" handle multiarch installations. I've
tested this on both Debian unstable and the latest Ubuntu which both use
this setup, and this appears to work largely the same way as GCC does.
It isn't exactly the same, but it is close enough and more principled in
its behavior where it differs. This should resolve any failures to find
'crt1.o' etc on Debian-based Linux distributions. If folks find more
cases where we fail, please file bugs and CC me.

Test cases for all of the debian silliness are waiting both to simplify
the process of merging these down into the 3.0 release, and because
they're so crazy I haven't yet been able to really produce a fake tree
that represents what we need to test for. I'll eventually add them
though.
