Simplify use of formatted_raw_ostream.

formatted_raw_ostream is a wrapper over another stream to add column and line
number tracking.

It is used only for asm printing.

This patch moves the its creation down to where we know we are printing
assembly. This has the following advantages:

* Simpler lifetime management: std::unique_ptr
* We don't compute column and line number of object files :-)

[SEH] Outline finally blocks using the new variable capture support

WinEHPrepare was going to have to pattern match the control flow merge

Now we can teach WinEHPrepare to pattern match this, which is much
simpler:

  call void @func(iN [01], i8* %fp)

Properly implement warn_unused_result checking for classes/structs.

The previous implementation would copy the attribute from the class to
functions that have the class as their return type when the functions
are first declared. This proved to have two flaws:
  1) if the class is forward-declared without the attribute and a
     function or method with the class as a its return type is declared,
     and afterward the class is defined with warn_unused_result, the
     function or method would never inherit the attribute, and
  2) the check simply failed for functions and methods that are part of
     a template instantiation, regardless of whether the class with
     warn_unused_result is part of a specific instantiation or part of
     the template itself (presumably because those function/method
     declaration does not hit the same code path as a non-template one
     and so never inherits the attribute).

The new approach is to instead modify the two places where a function or
method call is checked for the warn_unused_result attribute on the decl
by extending the checks to also look for the attribute on the decl's
return type.

Additionally, the check for return types that have the warn_unused_result
now excludes pointers and references to such types, as such return types do
not necessarily imply a transfer of ownership for the underlying object
being referred to by the return value. This does not change the behavior
of functions that are directly given the warn_unused_result attribute.

[IRForTarget] Strenghten handling of alternate mangling.

Summary:
This fixes an issue with GCC generated binaries wherein an expression
with method invocations on std::string variables was failing. Such use
cases are tested in TestSTL (albeit, in a test marked with
@unittest2.expectedFailure because of other reasons).

The reason for this particular failure with GCC is that the generated
DWARF for std::basic_string<...> is incomplete, which makes clang not
to use the alternate mangling scheme. GCC correctly generates the name
of basic_string<...>:

DW_AT_name "basic_string<char, std::char_traits<char>, std::allocator<char> >"

It also lists the template parameters of basic_string correctly:

DW_TAG_template_type_parameter
    DW_AT_name                  "_CharT"
    DW_AT_type                  <0x0000009c>
DW_TAG_template_type_parameter
    DW_AT_name                  "_Traits"
    DW_AT_type                  <0x00000609>
DW_TAG_template_type_parameter
    DW_AT_name                  "_Alloc"
    DW_AT_type                  <0x000007fb>

However, it does not list the template parameters of std::char_traits<>.
This makes Clang feel (while parsing the expression) that the string
variable is not actually a basic_string instance, and consequently does
not use the alternate mangling scheme.

Test Plan:
dotest.py -C gcc -p TestSTL
          -- See it go past the "for" loop expression successfully.

Summary:
Previously the Debugger::HandleProcessEvent hid a top IOHandler if the

IOHandler.Refresh() prints the (lldb) prompt. The problem was in case of
iOS remote platform when trying to execute 'command source' command.
On this platform the process's IOHandler is empty, therefore the
Debugger::HandleProcessEvent hid a top IOHandler and later refreshed it.
So that the (lldb) prompt was printed with a program output in mixed

Process the -freciprocal-math optimization flag (PR20912)

The driver currently accepts but ignores the -freciprocal-math flag.
This patch passes the flag through and enables 'arcp' fast-math-flag
generation in IR.

Note that this change does not actually enable the optimization for

was implemented by http://reviews.llvm.org/D6334 :
http://llvm.org/viewvc/llvm-project?view=revision&revision=222510

Because the optimization is done in the backend rather than IR,
the backend must be modified to understand instruction-level
fast-math-flags or a new function-level attribute must be created.

Also note that -freciprocal-math is independent of any target-specific
usage of reciprocal estimate hardware instructions. That requires
its own flag ('-mrecip').

Refactor CMICmnLLDBDebuggerHandleEvents/CMICmnLLDBDebugSessionInfo/CMICmnLLDBDebugSessionInfoVarObj (MI)

Summary:
This patch includes the following changes:

# Refactor GetVariableInfo/GetValueStringFormatted/GetValue to use the same code (MI)
Also it expands the variable value format for strings (aka char*):
was:
```
^done,name="v4",numchild="1",value="0x0000000100000f56",type="const char *",thread-id="1",has_more="0"
```
now:
```
^done,name="v4",numchild="1",value="0x0000000100000f56 \"ab\"",type="const char *",thread-id="1",has_more="0"
```

# Expand the variable value format for arrays (according to GDB)
For example:
was:
```
^done,name="v3",numchild="2",value="{...}",type="char [2]",thread-id="1",has_more="0"
```
now:
```
^done,name="v3",numchild="2",value="[2]",type="char [2]",thread-id="1",has_more="0"
```

llvm-svn: 234451

Separate atom_collection type into two different types. NFC.

atom_collection is basically a wrapper for std::vector. The class
provides begin and end member functions, so that it "hides" the
other member functions provided by std::vector. However, you can
still directly access _atoms member since the member is not
protected.

We cannot simply make the member private because we need that member
when we are constructing atom vectors.

This patch splits atom_collection into two types: std::vector<Atom *>
and AtomRange. When we are constructing atom vectors, we use the
former class. We return instances of the latter class from File
objects so that callers cannot add or remove atoms from the lists.

std::vector<Atom *> is automatically converted to AtomRange.

but it's close enough.
