[PowerPC] Remove incorrect use of COPY_TO_REGCLASS in fast isel
The fast isel pass currently emits a COPY_TO_REGCLASS node to convert
from a F4RC to a F8RC register class during conversion of a
floating-point number to integer. There is actually no support in the
common code instruction printers to emit COPY_TO_REGCLASS nodes, so the
PowerPC back-end has special code there to simply ignore
COPY_TO_REGCLASS.
This is correct *if and only if* the source and destination registers of
COPY_TO_REGCLASS are the same (except for the different register class).
But nothing guarantees this to be the case, and if the register
allocator does end up allocating source and destination to different
registers after all, the back-end simply generates incorrect code. I've
included a test case that shows such incorrect code generation.
However, it seems that COPY_TO_REGCLASS is actually not intended to be
used at the MI layer at all. It is used during SelectionDAG, but always
lowered to a plain COPY before emitting MI. Other back-end's fast isel
passes never emit COPY_TO_REGCLASS at all. I suspect it is simply wrong
for the PowerPC back-end to emit it here.
This patch changes the PowerPC back-end to directly emit COPY instead of
COPY_TO_REGCLASS and removes the special handling in the instruction
printers.

[CodeGenCXX] Fix ItaniumCXXABI::getAlignmentOfExnObject to return 8-byte
alignment on Darwin.
Itanium C++ ABI specifies that _Unwind_Exception should be double-word
aligned (16B). To conform to the ABI, libraries implementing exception
handling declare the struct with __attribute__((aligned)), which aligns
the unwindHeader field (and the end of __cxa_exception) to the default
target alignment (which is typically 16-bytes).
struct __cxa_exception {
...
// struct is declared with __attribute__((aligned)).
_Unwind_Exception unwindHeader;
};
Based on the assumption that _Unwind_Exception is declared with
__attribute__((aligned)), ItaniumCXXABI::getAlignmentOfExnObject returns
the target default alignment for __attribute__((aligned)). It turns out
that libc++abi, which is used on Darwin, doesn't declare the struct with
the attribute and therefore doesn't guarantee that unwindHeader is
aligned to the alignment specified by the ABI, which in some cases
causes the program to crash because of unaligned memory accesses.
This commit avoids crashes due to unaligned memory accesses by having
getAlignmentOfExnObject return an 8-byte alignment on Darwin. I've only
fixed the problem for Darwin, but we should also figure out whether other
platforms using libc++abi need similar fixes.

Changes in <__tree>
* Add traits to detect, handle, and unwrap, map's "__value_type".
* Convert methods taking "value_type" to take "__container_value_type" instead. Previously these methods caused
unwanted implicit conversions from "std::pair<Key, Value>" to "__value_type<Key, Value>".
* Delete __tree_node and __tree_node_base's constructors and assignment operators. The node types should never be constructed
because the "__value_" member of __tree_node must be constructed directly by the allocator.
* Make the __tree_node_destructor class and "__construct_node" methods unwrap "__node_value_type" into "__container_value_type" before invoking the allocator. The user's allocator can only be used to construct and destroy the container's value_type. Passing it map's "__value_type" was incorrect.
* Cleanup the "__insert" and "__emplace" methods. Have __insert forward to an __emplace function wherever possible to reduce
code duplication. __insert_unique(value_type const&) and __insert_unique(value_type&&) forward to __emplace_unique_key_args.
These functions will not allocate a new node if the value is already in the tree.
* Change the __find* functions to take the "key_type" directly instead of passing in "value_type" and unwrapping the key later.
This change allows the find functions to be used without having to construct a "value_type" first. This allows for a number
of optimizations.
* Teach __move_assign and __assign_multi methods to unwrap map's __value_type.

Fix case confusion.
The test case was defining and using a function 'notExported()', but
the FileCheck checks were checking for the name 'not_exported'. This
changes the test to use 'notExported' across the board. Also, the test
defined a function 'not_defined()', but doesn't have any checks related
to it. For consistency, this name is changed to 'notDefined'. A later

Remove unused variants of make_dynamic_error_code. NFC.
make_dynamic_error_code was used to create a std::error_code with
a std::string message. Now that we are migrating to llvm::Error,
there are no calls to these make_dynamic_error_code methods.
There is one single call to make_dynamic_error_code remaining, the one
inside GenericError::convertToErrorCode(). That method is only called
from File::doParse() which should be a temporary situation. We need
to work out how to deal with File::parse() caching the error result from
doParse(). Caching errors isn't supported in the new scheme, and probably
isn't needed here, but we need to work that out.

[Sema] Fix PR27122: ICE with enable_if+ill-formed call.
In some cases, when we encounter a direct function call with an
incorrect number of arguments, we'll emit a diagnostic, and pretend that
the call to the function was valid. For example, in C:
int foo();
int a = foo(1);
Prior to this patch, we'd get an ICE if foo had an enable_if attribute,
because CheckEnableIf assumes that the number of arguments it gets
passed is valid for the function it's passed. Now, we check that the
number of args looks valid prior to checking enable_if conditions.
This fix was not done inside of CheckEnableIf because the problem
presently can only occur in one caller of CheckEnableIf (ActOnCallExpr).
Additionally, checking inside of CheckEnableIf would make us emit
multiple diagnostics for the same error (one "enable_if failed", one
"you gave this function the wrong number of arguments"), which seems
worse than just complaining about the latter.

[CrashReproducer] Add a module map callback for added headers
The current ModuleDependencyCollector has a AST listener to collect
header files present in loaded modules, but this isn't enough to collect
all headers needed in the crash reproducer. One of the reasons is that
the AST writer doesn't write symbolic link header paths in the pcm modules,
this makes the listeners on the reader only able to collect the real files.
Since the module maps could contain submodules that use headers which
are symbolic links, not collecting those forbid the reproducer scripts
to regen the modules.
For instance:
usr/include/module.map:
...
module pthread {
header "pthread.h"
export *
module impl {
header "pthread_impl.h"
export *
}
}
...
usr/include/pthread/pthread_impl.h
usr/include/pthread_impl.h -> pthread/pthread_impl.h
The AST dump for the module above:
<SUBMODULE_HEADER abbrevid=6/> blob data = 'pthread_impl.h'
<SUBMODULE_TOPHEADER abbrevid=7/> blob data = '/<path_to_sdk>/usr/include/pthread/pthread_impl.h'
Note that we don't have "usr/include/pthread_impl.h" which is requested
by the module.map in case we want to reconstruct the module in the
reproducer. The reason the original symbolic link path isn't used is
because the headers are kept by name and requested through the
FileManager, which unique files and returns the real path only.
To fix that, add a callback to be invoked everytime a header is added
while parsing module maps and hook that up to the module dependecy
collector. This callback is only registered when generating the
reproducer.
