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.

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.

It’s important for us to reason about the cast as it is used in std::addressof. The reason we did not
handle the cast previously was a crash on a test case (see commit r157478). The crash was in
processing array to pointer decay when the region type was not an array. Address the issue, by
just returning an unknown in that case.

This patch solves the problem of numeric register values not being accepted:
../set_alias.s:1:11: error: expected valid expression after comma
.set r4,$4
^
The parsing of .set directive is changed and handling of symbols in code
as well to enable this feature.
The test example is added.

- added code for tracking transition from eStateAttaching to eStateStopped in event listener and handling process continuation there.

- llvm.loop.parallel metadata has been renamed to llvm.loop to be more generic
by making the root of additional loop metadata.
- Loop::isAnnotatedParallel now looks for llvm.loop and associated
llvm.mem.parallel_loop_access
- document llvm.loop and update llvm.mem.parallel_loop_access
- add support for llvm.vectorizer.width and llvm.vectorizer.unroll
- document llvm.vectorizer.* metadata
- add utility class LoopVectorizerHints for getting/setting loop metadata
- use llvm.vectorizer.width=1 to indicate already vectorized instead of
already_vectorized
- update existing tests that used llvm.loop.parallel and
llvm.vectorizer.already_vectorized

Previously we would read-modify-write the target bits when processing
relocations for the MCJIT. This had the problem that when relocations
were processed multiple times for the same object file (as they can
be), the result is not idempotent and the values became corrupted.
The solution to this is to take any bits used in the destination from
the pristine object file as LLVM emitted it.
This should fix PR16013 and remote MCJIT on ARM ELF targets.

Before this patch the linkage cache was only used by the entry level function
(getLinkage). The function that does the actual computation (getLVForDecl),
never looked at it.
This means that we would not reuse an entry in the cache when getLVForDecl did
a recursive call. This patch fixes that by adding another computation enum
value for when we don't care about the linkage at all and having getLVForDecl
check the cache in that case.
When running "clang -cc1" over SemaExpr.ii this brings the number of linkage
computations from 93749 to 58426. When running "clang -cc1 -emit-llvm -O3" it
goes from 198708 to 161444.
For SemaExpr.ii at least linkage computation is a small enough percentage of
the work that the time difference was in the noise.
When asserts are enabled this patch also causes clang to check the linkage
cache even on recursive calls.
