9dd8c0cffe Option parsing: add support for alias arguments.
This makes option aliases more powerful by enabling them to
pass along arguments to the option they're aliasing.

For example, if we have a joined option "-foo=", we can now
specify a flag option "-bar" to be an alias of that, with the
argument "baz".

This is especially useful for the cl.exe compatible clang driver,
where many options are aliases. For example, this patch enables
us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to
"-Werror" (again, -W is a joined option).

c1bb2d4325 Use pipefail when available.
This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.

563a9cf7ba Fix a bug in TableGen where the intrinsic function name recognizer could mis-identify names if one was a prefix substring of the other
For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal',
TableGen was emitting matching code like:

  if (Name.startswith("llvm.nvvm.texsurf.handle")) ...
  if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ...

We can never match "llvm.nvvm.texsurf.handle.internal" here because it will
always be erroneously matched by the first condition.

The fix is to sort the intrinsic names and emit them in reverse order.

ba46086444 lit: Support cancellation on Windows
The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.

We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.

178504b07b Add new directive called CHECK-LABEL to FileCheck.
CHECK-LABEL is meant to be used in place on CHECK on lines containing identifiers or other unique labels (they need not actually be labels in the source or output language, though.) This is used to break up the input stream into separate blocks delineated by CHECK-LABEL lines, each of which is checked independently. This greatly improves the accuracy of errors and fix-it hints in many cases, and allows for FileCheck to recover from errors in one block by continuing to subsequent blocks.

Some tests will be converted to use this new directive in forthcoming patches.

ac226bbf45 Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.
Summary:
This patch adds explicit calling convention types for the Win64 and
System V/x86-64 ABIs. This allows code to override the default, and use
the Win64 convention on a target that wants to use SysV (and
vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU
attributes.

Now the two possible uses of not are

  Will return true if cmd crashes.

It will be used/tested in a followup commit for the clang crash recovery

b7110cf5b5 Improve the compression of the tablegen DiffLists by introducing a new sort
algorithm when assigning EnumValues to the synthesized registers.

The current algorithm, LessRecord, uses the StringRef compare_numeric
function.  This function compares strings, while handling embedded numbers.
For example, the R600 backend registers are sorted as follows:

  T1
  T1_W
  T1_X
  T1_XYZW
  T1_Y
  T1_Z
  T2
  T2_W
  T2_X
  T2_XYZW
  T2_Y
  T2_Z

In this example, the 'scaling factor' is dEnum/dN = 6 because T0, T1, T2
have an EnumValue offset of 6 from one another.  However, in other parts
of the register bank, the scaling factors are different:

dEnum/dN = 5:
  KC0_128_W
  KC0_128_X
  KC0_128_XYZW
  KC0_128_Y
  KC0_128_Z
  KC0_129_W
  KC0_129_X
  KC0_129_XYZW
  KC0_129_Y
  KC0_129_Z

The diff lists do not work correctly because different kinds of registers have
different 'scaling factors'.  This new algorithm, LessRecordRegister, tries to
enforce a scaling factor of 1.  For example, the registers are now sorted as
follows:

  T1
  T2
  T3
  ...
  T0_W
  T1_W
  T2_W
  ...
  T0_X
  T1_X
  T2_X
  ...
  KC0_128_W
  KC0_129_W
  KC0_130_W
  ...

For the Mips and R600 I see a 19% and 6% reduction in size, respectively.  I
did see a few small regressions, but the differences were on the order of a
few bytes (e.g., AArch64 was 16 bytes).  I suspect there will be even
greater wins for targets with larger register files.
