Summary:
Reorder the condition code enum to match their encodings. Move it to MC layer so it can be used by the scheduler models.

This avoids needing an isel pattern for each condition code. And it removes
translation switches for converting between CMOV instructions and condition
codes.

Now the printer, encoder and disassembler take care of converting the immediate.
We use InstAliases to handle the assembly matching. But we print using the
asm string in the instruction definition. The instruction itself is marked
IsCodeGenOnly=1 to hide it from the assembly parser.

This does complicate the scheduler models a little since we can't assign the
A and BE instructions to a separate class now.

I plan to make similar changes for SETcc and Jcc.

architectures mask the shift count to 5 bits which limits the number of
shifts inside a range of 0 to 31. Shifting by 32 has the same effect as
shifting by 0, so if the first bit in the set is 1, the function will return
with Index different from EndIndexVal. Because of that, range-based for
loops iterating thorough architectures will continue until hitting a 0 in
the set, resulting in n additional iterations, where n is equal to the
number of consecutive 1 bits at the start the set.

Minidump: Add support for reading/writing strings

Summary:
Strings in minidump files are stored as a 32-bit length field, giving
the length of the string in *bytes*, which is followed by the
appropriate number of UTF16 code units. The string is also supposed to
be null-terminated, and the null-terminator is not a part of the length
field. This patch:
- adds support for reading these strings out of the minidump file (this
  implementation does not depend on proper null-termination)
- adds support for writing them to a minidump file
- using the previous two pieces implements proper (de)serialization of
  the CSDVersion field of the SystemInfo stream. Previously, this was
  only read/written as hex, and no attempt was made to access the
  referenced string -- now this string is read and written correctly.

The changes are tested via yaml2obj|obj2yaml round-trip as well as a
unit test which checks the corner cases of the string deserialization
logic.

[SelectionDAG] Compute known bits of CopyFromReg

Summary:
Teach SelectionDAG how to compute known bits of ISD::CopyFromReg if
the virtual reg used has one def only.

This can be particularly useful when calling isBaseWithConstantOffset()
with the ISD::CopyFromReg argument, as more optimizations may get enabled
in the result.

Also add a missing truncation on X86, found by testing of this patch.

5 years ago[llvm-symbolizer] Add `--output-style` switch.

[llvm-symbolizer] Add `--output-style` switch.

In general, llvm-symbolizer follows the output style of GNU's addr2line.
However, there are still some differences; in particular, for a requested
address, llvm-symbolizer prints line and column, while addr2line prints
only the line number.

This patch adds a new switch to select the preferred style.
