When a prefix is passed, we need to print a colon a space after it, not
just the prefix.

[X86] Remove DATA32_PREFIX. Hack the printing for DATA16_PREFIX to print 'data32' in 16-bit mode. Hack the asm parser to convert 'data32' to 'data16' in 16-bit mode.

Improve the error messages to match GNU assembler.

This also allows us to remove the hack from the disassembler table building.

Add tests for the improved stream type detection added to
`llvm-bcanalyzer` in https://reviews.llvm.org/D41979.

Summary:
`llvm-bcanalyzer` prints out the stream type of the file it is
analyzing. If the file begins with the LLVM IR magic number, it reports
a stream type of "LLVM IR". However, any other bitstream format is
reported as "unknown".

Add some checks for two other common bitstream formats: Clang AST
files, which begin with 'CPCH', and Clang serialized diagnostics, which
begin with 'DIAG'.

This commit has been breaking most bots for a day now. There is a fix
proposed in https://reviews.llvm.org/D45912 but when I applied that
I just got different errors. Reverting to get our bots back to green.

A future patch will turn this into MULHU/MULHS.

The current way that the lit configuration is generated for the LLDB
tests that run using dotest causes cmake to fail when using a generator
which supports multiple configurations (such as Visual Studio). The
failure is because file GENERATE will create a file *per possible
configuration* resulting in the same lit configuration file being
overwritten multiple times.

To fix the issue, we need to create a single lit file that is agnostic
of the configurations and can be used for any configuration.

The patch introduces a new command line option '-check-suffix' for check_clang_tidy.py 
to allow multiple %check_clang_tidy% in a single test file.

Sample:

// RUN: %check_clang_tidy -check-suffix=FLAG-1 %s misc-unused-using-decls %t -- -- <options-set-1>
// RUN: %check_clang_tidy -check-suffix=FLAG-2 %s misc-unused-using-decls %t -- -- <options-set-2> 
...
+// CHECK-MESSAGES-FLAG-1: :[[@LINE-4]]:10: warning: using decl 'B' is unused [misc-unused-using-decls]

Fix testing of clang_File_tryGetRealPathName() in
LibclangReparseTest.FileName when executing in an environment which has
TMPDIR set to a symbolic link that points to an actual directory. The
test would fail because the name returned by
clang_File_tryGetRealPathName() has the symlink resolved but the test
compared it to the original filename of a temporary file.

The patch addresses the problem by checking only that the value returned
by clang_File_tryGetRealPathName() ends with "main.cpp".

Additionally, the patch makes the previous assertion in the test that
checks result of clang_getFileName() stricter. It newly verifies that
the name returned by the function is exactly same as what was given to
clang_parseTranslationUnit()/clang_getFile().

Now, if DoReadMemory or DoWriteMemory encounters error then return 0
