[CodeGen] Enable tail call position check for speculatable functions

In the function "Analysis.cpp:isInTailCallPosition", it only checks whether
a call is in a tail call position if the call has side effects, access memory
or it is not safe to speculative execute. Therefore, a speculatable function
will not go through tail call position check and improperly tail called when
it is not in a tail-call position. This patch enables tail call position check
for speculatable functions.

[analyzer] Add support for ObjCIndirectCopyRestoreExpr.

Idiomatic objc using ARC will generate this expression regularly due to
NSError out-param passing.  Providing an implementation for this
expression allows the analyzer to explore many more codepaths in ARC

The current implementation is not perfect but the differences are hopefully
subtle enough to not cause much problems.

[analyzer] ObjCAutoreleaseWriteChecker: Support explicit autoreleasepools.

The checker currently supports only a whitelist of block-enumeration
methods which are known to internally clear an autorelease pool.
Extend this checker to detect writes within the scope of explicit
@autoreleasepool statements.

[libc++] Support move construction and assignment in <thread> in C++03

Libc++ provides support for <thread> in C++03 as an extension. Furthermore,
it does not support any compiler that doesn't have rvalue references. It
is hence possible to provide the move constructor and move assignment
operator in C++03.

[MLIR] Shape to standard dialect lowering

Add a new pass to lower operations from the `shape` to the `std` dialect.
The conversion applies only to the `size_to_index` and `index_to_size`
operations and affected types.
Other patterns will be added as needed.
