Chandler Carruth 4d88a1c233 Sort the #include lines for tools/...
Again, tools are trickier to pick the main module header for than
library source files. I've started to follow the pattern of using
LLVMContext.h when it is included as a stub for program source files.

Rafael Espindola a339e47689 libLTO has a bug in that it will keep every symbol if none is needed. We used
to hack around this in the gold plugin by deleting a module if no symbol was
needed. Unfortunately, the hack is wrong in the case of o module having no
visible symbols but still having side effects via static constructors.

The bug will have to be fixed in libLTO itself.

Rafael Espindola 9aa1fcce58 Use LTO_CODEGEN_PIC_MODEL_DYNAMIC for PIE. This requirest a git version of
gold to work. Since the enum value LDPO_PIE has just been added to plugin-api.h,
use a numeric constant for now so that we don't require an unreleased
version of gold to build.

Ivan Krasin 639222d090 use 64-bit types instead of off_t/size_t to avoid the issue when
gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686)
and the rest of LLVM is built w/o Large File Support
(sizeof(off_t) == 32 on i686) which corrupts the stack.

Rafael Espindola ef49815638 Add an extra-library-path option to the plugin. This is used to support
having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.

Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.

Rafael Espindola 8297640062 Add a pass-through option to the plugin. The use case for this option is to
ask the linker to take another look into some library or object. The case when
one might want to do this is when codegen introduces a new undefined reference.
The canonical example is libgcc.

Dan Gohman 61a8796ddb Make LLVM command-line tools overwrite their output files without -f.
This is conventional command-line tool behavior. -f now just means
"enable binary output on terminals".

Add a -f option to llvm-extract and llvm-link, for consistency.

Remove F_Force from raw_fd_ostream and enable overwriting and
truncating by default. Introduce an F_Excl flag to permit users to
enable a failure when the file already exists. This flag is
currently unused.

Update Makefiles and documentation accordingly.

Chris Lattner 9e6f1f160a Change raw_fd_ostream to take flags as an optional bitmask
instead of as two bools.  Use this to add a F_Append flag
which has the obvious behavior.

Other unrelated changes conflated into this patch:

1. REmove EH stuff from llvm-dis and llvm-as, the try blocks
   are dead.
2. Simplify the filename inference code in llvm-as/llvm-dis,
   because raw_fd_ostream does the right thing with '-'.
3. Switch machine verifier to use raw_ostream instead of ostream
   (Which is the thing that needed append in the first place).

Dan Gohman 607818a2c1 Add a Force option to raw_fd_ostream to specify whether opening
