Revert r127073: "Introduce $(ECHOPATH) to print DOSish path string on MSYS bash for alternative of $(ECHO)."

It broke the llvm-gcc-native-mingw32 buildbot, and we need all of them to be green for the 2.9 branch.

Takumi, please reapply after we branch, preferably with a fix ;-)

utils/lit/lit/TestRunner.py: bash is available with MSYS on Python/W32. Then we can execute "bash tests".

On mingw and python/w32, lit would not be expected to understand MSYS-style path.

On Windows hosts, Python scripts in test/Scripts did not accept binary files from stdin. The environment variable "PYTHONUNBUFFERED" makes stdin as binary. Thanks to Danil Malyshev!

equal to the number of jobs and launch one jobs on each
thread.  This makes things work like make -j.

   InstAlias<{alias}, {aliasee}>;

The InstAlias instruction should be able to go from the MCInst to the
{alias}. All of the information is there to match the MCInst with the
{aliasee}. From there, it's a simple matter to emit the {alias}, with the
correct operands from the {aliasee}.

The code this patch generates can be used by the InstPrinter to automatically
print out the alias without having to write special C++ code to handle the
situation.

This is a WIP, and therefore are several limitations. For instance, it cannot
handle AsmOperands at the moment. It also doesn't know what to do when two
{alias}es match the same {aliasee}. (Currently, it just ignores those two cases
and allows the printInstruction method to handle them.)

This one just installs the default build into a different destination directory.

Add some options for building LLVM in different environments:

--force-configure to force running configure before building.

--extra-llvm-config-flags
--extra-llvm-gcc-config-flags
--extra-gcc-config-flags

Pass additional argument to the various configure invocations.

This also eliminates a default build flavor because explicitly
specifying builds could result in build flavors being run repeatedly.

Finally, turn off fortran builds for the moment because install
appears to be broken.

Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for fixed-length instruction encodings.
A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks
provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen
like the existing disassembly emitters do.

The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove
some of the hacks the old one introduced to tblgen.

lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this.

FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

- Add custom operand matching for imod and iflags.
- Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC
  from mnemonic.
- While adding ".w" as an operand, don't change "Head" to avoid passing the
  wrong mnemonic to ParseOperand.
- Add asm parser tests.
- Add disassembler tests just to make sure it can catch all cps versions.

Teach the AsmMatcher handling to distinguish between an error custom-parsing
an operand and a failure to match. The former should propogate the error
upwards, while the latter should continue attempting to parse with
alternative matchers.

Update the ARM asm parser accordingly.
