MSVC's class data is always comdat, so clang's should always be
linkonce_odr in LLVM IR.

newFrontendActionFactory() took a pointer to a callback to call when a source
file was done being processed by an action. This revision updates the callback
to include an ante-processing callback as well.
Callback-providing class renamed and callback functions themselves renamed.
Functions are no longer pure-virtual so users aren't forced to implement both
callbacks if one isn't needed.

Tidy up three places where the register class for ARM and Thumb wasn't
restrictive enough:
- No PC dest for reg-reg add/orr/sub.
- No PC dest for shifts.
- No PC or SP for Thumb2 reg-imm add.
I encountered this while combining FastISel with
-verify-machineinstrs. These instructions defined registers whose
classes weren't restrictive enough, and the uses failed
verification. They're also undefined in the ISA, or would produce code
that FastISel wouldn't want. This doesn't fix the register class
narrowing issue (where uses should restrict definitions), and isn't
thorough, but it's a small step in the right direction.

Now that the TokenAnnotator does not require stack space anymore,
reconstructing the lines has become the limiting factor. This patch
fixes that problem, allowing large files with multiple megabytes of
single unwrapped lines to be formatted.

- The original test now passes on Linux with clang because a breakpoint is hit prior to evaluation of text_list, which improves text coverage.
- The new test fails because 4 steps are requested, and only two occur prior to evaluation of text_list.
--- Note that the loss of every second "next" command can be reproduced using lldb manually with this script.

Gets rid of AnnotatedToken, putting everything into FormatToken.
FormatTokens are created once, and only referenced by pointer. This
enables multiple future features, like having tokens shared between
multiple UnwrappedLines (while there's still work to do to fully enable
that).

If an identifier is on its own line and it is all upper case, it is highly
likely that this is a macro that is meant to stand on a line by itself.
Before:
class A : public QObject {
Q_OBJECT A() {}
};
Ater:
class A : public QObject {
Q_OBJECT
A() {}
};

Instead of using arch_prctl(ARCH_GET_FS), read the address from the
tread descriptor itself. This lets us avoid sandboxing issues. Also,
GetThreadStackAndTls() can now be implemented on i386.

With option enabled (e.g. in Google-style):
template <typename T>
void f() {}
With option disabled:
template <typename T> void f() {}
Enabling this for Google-style and Chromium-style, not sure which other
styles would prefer that.

This brings the number of linkage computations in "clang -cc1" in SemaExpr.ii
from 58426 to 43134. With -emit-llvm the number goes from 161045 to 145461.

This updates the debug info metadata schema documentation for various
schema changes made recently surrounding filename information for
scopes and the representation of imported entities.
llvm-svn: 182817
This gives slightly better precision, specifically, in cases where a non-typed region represents the array
or when the type is a non-array type, which can happen when an array is a result of a reinterpret_cast.
