John McCall 47fb950871 Change hasAggregateLLVMType, which conflates complex and
aggregate types in a profoundly wrong way that has to be
worked around in every call site, to getEvaluationKind,
which classifies and distinguishes between all of these
cases.

Also, normalize the API for loading and storing complexes.

I'm working on a larger patch and wanted to pull these
changes out, but it would have be annoying to detangle
them from each other.

David Blaikie 0a21d0da17 PR14566: Debug Info: avoid top level lexical blocks in functions
One of the gotchas (see changes to CodeGenFunction) was due to the fix in
r139416 (for PR10829). This only worked previously because the top level
lexical block would set the location to the end of the function, the debug
location would be updated (as per r139416), the location would be set to
the end of the function again (but that would no-op, since it was the same
as the previous location), then the return instruction would be emitted using
the debug location.

Once the top level lexical block was no longer emitted, the end-of-function
location change was causing the debug loc to be updated, regressing that bug.

Chandler Carruth ffd5551bc7 Rewrite #includes for llvm/Foo.h to llvm/IR/Foo.h as appropriate to
reflect the migration in r171366.

Re-sort the #include lines to reflect the new paths.

Bill Wendling 7967fc14b9 Rename the 'Attributes' class to 'Attribute'. It's going to represent a single attribute in the future.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Bill Wendling 311c832fda Attributes Rewrite
Convert the uses of the Attributes class over to the new format. The
Attributes::get method call now takes an LLVM context so that the attributes
object can be uniquified and stored.

intended.

John McCall b0433eeb2e During jump-scope checking, build an ExprWithCleanups immediately
into the enclosing scope;  this is a more accurate model but is
(I believe) unnecessary in my test case due to other flaws.
However, one of those flaws is now intentional:  blocks which
appear in return statements can be trivially observed to not
extend in lifetime past the return, and so we can allow a jump
past them.  Do the necessary magic in IR-generation to make
this work.

Chad Rosier 85fff2ac11 [ms-inline asm] Remove the Inline Asm Non-Standard Dialect attribute. This

Chad Rosier 6051bb94c0 [ms-inline asm] Rename EmitGCCAsmStmt to EmitAsmStmt and have it accept
AsmStmts.  This function is only used by GCCAsmStmts, however. Constraints need
to be properly computed before MSAsmStmts can use EmitAsmStmt.  No functional
change intended.

codegen logic for AsmStmts.

Chad Rosier 175ea24e38 [ms-inline asm] Change the -fenable-experimental-ms-inline-asm option from a
CodeGen option to a LangOpt option.  In turn, hoist the guard into the parser 
so that we avoid the new (and fairly unstable) Sema/AST/CodeGen logic.  This
should restore the behavior of clang to that prior to r158325.

Chad Rosier d997bd1422 [ms-inline asm] Start sending non-simple inline asms to the AsmParser.
The parser still can't handle all cases, so fall back to emitting a simple
MSAsmStmt if we get into trouble.

Chad Rosier 43b7c021b3 [ms-style asm] Change the fatal error to an extension warning. Apparently, this

Richard Smith c202b2809a Add an AttributedStmt type to represent a statement with C++11 attributes
attached. Since we do not support any attributes which appertain to a statement
(yet), testing of this is necessarily quite minimal.
