Mehdi Amini b550cb1750 [NFC] Header cleanup
Removed some unused headers, replaced some headers with forward class declarations.

Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'

Zachary Turner 4d5535a70a Fix some display bugs in llvm-pdbdump.
We were incorrectly reporting all non-64 bit integers as int64s.
This is most evident when trying to print the "short" type, but
in theory could happen with chars too (although usually chars use
a different builtin type).

Additionally, we were using the wrong check when deciding whether
to print an enum definition as a global enum.  We were checking
whether or not the enum was "nested", and if so saving it until
we print the class definition that it was nested in.  But this is
not correct in rare situations where the enum is nested, but the
class that it's nested in does not have type information in the PDB.
So instead we check if there is a class definition for the parent
in the PDB.  If so we save it for later, otherwise we print it.

Summary:
This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html

Reid Kleckner 72e2ba7abb [readobj] Expand CodeView dumping functionality
This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.

The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.

David Majnemer 6e08126f31 [llvm-pdbdump] Provide a mechanism to dump the raw contents of a PDB
A PDB can be thought of as a very simple file system.  It is
occasionally illuminating to see the contents of the underlying files.

Zachary Turner 4dddcc64d3 [llvm-pdbdump] Add include-only filters.
PDB files have a lot of noise in them, with hundreds (or thousands)
of symbols from system libraries and compiler generated types.  If
you're only looking for a specific type, this can be problematic.

This CL allows you to display *only* types, variables, or compilands
matching a particular pattern.  These filters can even be combined
with exclude filters.  Include-only filters are given priority, so
that first the set of items to display is limited only to those that
match the include filters, and then the set of exclude filters is
applied to those.  If there are no include filters specified, then
it means "display everything".

Benjamin Kramer f5e2fc474d Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial types
If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.


Call sites were found with the ASTMatcher + some semi-automated cleanup.

memberCallExpr(
    argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
    on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),
    hasArgument(0, bindTemporaryExpr(
                       hasType(recordDecl(hasNonTrivialDestructor())),
                       has(constructExpr()))),
    unless(isInTemplateInstantiation()))

No functional change intended.

Zachary Turner e5cb269352 [llvm-pdbdump] Support dynamic load address and external symbols.
This patch adds the --load-address command line option to
llvm-pdbdump, which dumps all addresses assuming the module has
loaded at the specified address.

Additionally, this patch adds an option to llvm-pdbdump to support
dumping of public symbols (i.e. symbols with external linkage).

Zachary Turner 4b08354b0e [PDB] Support executables and source/line info.
Previously DebugInfoPDB could only load data for a PDB given a
path to the PDB.  It could not open an EXE and find the matching
PDB and verify it matched, etc.  This patch adds support for that
so that we can simply load debug information for a PDB directly.

Additionally, this patch extends DebugInfoPDB to support getting
source and line information for symbols.

Zachary Turner 653236596a [llvm-pdbdump] Display full enum definitions.
This will now display enum definitions both at the global
scope as well as nested inside of classes.  Additionally,
it will no longer display enums at the global scope if the
enum is nested.  Instead, it will omit the definition of
the enum globally and instead emit it in the corresponding
class definition.

Zachary Turner 7797c726b9 [llvm-pdbdump] Many minor fixes and improvements
A short list of some of the improvements:

1) Now supports -all command line argument, which implies many
   other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
   exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.

And a few other minor tweaks.

Zachary Turner ccf0415973 [llvm-pdbdump] Better error handling.
Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.

This patch adds proper error handling so that we can know exactly
what went wrong.

Zachary Turner d270d22f35 [llvm-pdbdump] Fix dumping of function pointers and basic types.
Function pointers were not correctly handled by the dumper, and
they would print as "* name".  They now print as
"int (__cdecl *name)(int arg1, int arg2)" as they should.

Also, doubles were being printed as floats.  This fixes that bug
as well, and adds tests for all builtin types. as well as a test
for function pointers.

Zachary Turner 29c69105fb [llvm-pdbdump] Add an option to dump full class definitions.
This adds the --class-definitions flag.  If specified, when dumping
types, instead of "class Foo" you will see the full class definition,
with member functions, constructors, access specifiers.

NOTE: Using this option can be very slow, as generating a full class
definition requires accessing many different parts of the PDB.

This increases the flexibility of how to dump different

to in the PDB library.

Zachary Turner c074de041b Add concrete type overloads to PDBSymbol::findChildren().
Frequently you only want to iterate over children of a specific
type (e.g. functions).  Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of.  With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

Zachary Turner a5549178f1 Rewrite llvm-pdbdump in terms of LLVMDebugInfoPDB.
This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.

It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.
