Michael Kruse dc5ce72afa Append new attributes to the end of an AttributeList.
Recommit of r335084 after revert in r335516.

... instead of prepending it at the beginning (the original behavior
since implemented in r122535 2010-12-23). This builds up an
AttributeList in the the order in which the attributes appear in the
source.

The reverse order caused nodes for attributes in the AST (e.g. LoopHint)
to be in the reverse order, and therefore printed in the wrong order in
-ast-dump. Some TODO comments mention this. The order was explicitly
reversed for enable_if attribute overload resolution and name mangling,
which is not necessary anymore with this patch.

The change unfortunately has some secondary effect, especially on
diagnostic output. In the simplest cases, the CHECK lines or expected
diagnostic were changed to the the new output. If the kind of
error/warning changed, the attributes' order was changed instead.

This unfortunately causes some 'previous occurrence here' hints to be
textually after the main marker. This typically happens when attributes
are merged, but are incompatible to each other. Interchanging the role
of the the main and note SourceLocation will also cause the case where
two different declaration's attributes (in contrast to multiple
attributes of the same declaration) are merged to be reverse. There is
no easy fix because sometimes previous attributes are merged into a new
declaration's attribute list, sometimes new attributes are added to a
previous declaration's attribute list. Since 'previous occurrence here'
pointing to locations after the main marker is not rare, I left the
markers as-is; it is only relevant when the attributes are declared in
the same declaration anyway.

Michael Kruse 41dd6ced2c Revert "Append new attributes to the end of an AttributeList."
This reverts commit r335084 as requested by David Jones and
Eric Christopher because of differences of emitted warnings.

Manman Ren ccf25bbf3f AvailabilityAttr: we accept "macos" as the platform name.
We continue accepting "macosx" but canonicalize it to "macos", When emitting
diagnostics, we use "macOS" instead of "OS X".

The PlatformName in TargetInfo is changed from "macosx" to "macos" so we can
directly compare the Platform in AvailabilityAttr with the PlatformName
in TargetInfo.

Aaron Ballman 317a77f1c7 Adding in parsing and the start of semantic support for __sptr and __uptr pointer type qualifiers. This patch also fixes the correlated __ptr32 and __ptr64 pointer qualifiers so that they are truly type attributes instead of declaration attributes.
For more information about __sptr and __uptr, see MSDN: http://msdn.microsoft.com/en-us/library/aa983399.aspx

Michael Han af02bbe84f [Sema][Attr]Fix alignment attribute printing.
Remove "IsMSDeclspec" argument from Align attribute since the arguments in Attr.td should
only model those appear in source code. Introduce attribute Accessor, and teach TableGen
to generate syntax kind accessors for Align attribute, and use those accessors to decide
if an alignment attribute is a declspec attribute.

Richard Smith 0cdcc98200 Replace AS_MSTypespec with AS_Keyword, for representing any attribute spelled
as a keyword. Rationalize existing attributes to use it as appropriate, and to
not lie about some __declspec attributes being GNU attributes. In passing,
remove a gross hack which was discarding attributes which we could handle. This
results in us actually respecting the __pascal keyword again.

Michael Han 9931593299 PR14922: when printing an attribute, use the real syntax of the attribute (GNU, C++11, MS Declspec) instead of hardcoded GNU syntax.
Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. 
This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute.
When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and
name, then passed to Attr that will use the index to print itself. 

Thanks to Richard Smith for the idea and review.
