250bfb1745 Remove the LLVM specific archive index.
Archive files (.a) can have a symbol table indicating which object
files in them define which symbols. The purpose of this symbol table
is to speed up linking by allowing the linker the read only the .o
files it is actually going to use instead of having to parse every
object's symbol table.

LLVM's archive library currently supports a LLVM specific format for
such table. It is hard to see any value in that now that llvm-ld is
gone:

* System linkers don't use it: GNU ar uses the same plugin as the
linker to create archive files with a regular index. The OS X ar
creates no symbol table for IL files, I assume the linker just parses
all IL files.

* It doesn't interact well with archives having both IL and native objects.

* We probably don't want to be responsible for yet another archive
format variant.

This patch then:

* Removes support for creating and reading such index from lib/Archive.
* Remove llvm-ranlib, since there is nothing left for it to do.

We should in the future add support for regular indexes to llvm-ar for
both native and IL objects. When we do that, llvm-ranlib should be
reimplemented as a symlink to llvm-ar, as it is equivalent to "ar s".

dafd1a6311 Do not to perform RUN line substitution of llc if that's prefixed by a hypnen
(-llc), similarly to the way it was done for clang and llvmc. 

This doesn't affect the upstream llvm tests but helps when developing custom
LLVM-based tools and testing them within the LLVM regression framework.

7207285e65 [SystemZ] Set up JIT/MCJIT test cases
This patch adds the necessary configuration bits and #ifdef's to set up
the JIT/MCJIT test cases for SystemZ.  Like other recent targets, we do
fully support MCJIT, but do not support the old JIT at all.  Set up the
lit config files accordingly, and disable old-JIT unit tests.

Patch by Richard Sandiford.

3ca3fc5632 [test] Use lit's shell test runner on Windows
Summary:
I did a local comparison between using bash and using lit's runner, and
more of the suite passes with lit than passes with bash.  Most of the
bash failures have to do with /dev/null, which is nonsensical on
Windows, but the lit runner handles it.

The lit shell runner is also much faster than bash, so I would expect
most Windows devs would want it by default.

The behavior can be overridden on any OS by setting
LIT_USE_INTERNAL_SHELL to 0 or 1 in the environment.

fbb662f840 Introduce llvm::sys::getProcessTriple() function.
In r143502, we renamed getHostTriple() to getDefaultTargetTriple()
as part of work to allow the user to supply a different default
target triple at configure time.  This change also affected the JIT.
However, it is inappropriate to use the default target triple in the
JIT in most circumstances because this will not necessarily match
the current architecture used by the process, leading to illegal
instruction and other such errors at run time.

Introduce the getProcessTriple() function for use in the JIT and
its clients, and cause the JIT to use it.  On architectures with a
single bitness, the host and process triples are identical.  On other
architectures, the host triple represents the architecture of the
host CPU, while the process triple represents the architecture used
by the host CPU to interpret machine code within the current process.
For example, when executing 32-bit code on a 64-bit Linux machine,
the host triple may be 'x86_64-unknown-linux-gnu', while the process
triple may be 'i386-unknown-linux-gnu'.

This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple
platforms.

4177e6fff5 Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

7e621f3242 Switch a bunch of Linker tests from using elaborate echo productions to
just provide and reference separate input files from an Inputs
subdirectory. This pattern works very well in the Clang tree and is
easier to understand in my opinion. It also has fewer limitations and
will remove one particularly annoying use of TCL-style {} quoting from
the testsuite.

Also teach the LLVM lit configuration to avoid recursing into 'Inputs'
subdirectories. This wasn't required for the previous 'Inputs'
subdirectories used due to fortuitous suffix patterns.

This is the first step to completely removing support for TCL-style tests.

96f41a1b0f Remove 'site.exp' building from both CMake and configure+make.
This is another vestige of the DejaGNU roots. There were FIXMEs in the
lit setup to add a 'lit.site.cfg', which has been around for quite some
time now, so I've properly switched the handling of the 4 things
actually used in site.exp to go through lit.site.cfg now. No more
parsing of the .exp file, one fewer configure-style generated file,
etc., etc.

75338097c7 Remove llvm-ld and llvm-stub (which is only used by llvm-ld).
llvm-ld is no longer useful and causes confusion and so it is being removed.

* Does not work very well on Windows because it must call a gcc like driver to
  assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
  ld, or fully replaced by Clang.

I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

f2a58425cd lit support for REQUIRES: asserts.
Take #2. Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.
