Chandler Carruth 9a67b07398 Re-sort #include lines for unittests. This uses a slightly modified
clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.

No other change was made. I did no manual edits, all of this is
clang-format.

This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

This reverts commit r297624.
It was failing on the bots.

Rafael Espindola 82d55239ea Fix crash when multiple raw_fd_ostreams to stdout are created.
If raw_fd_ostream is constructed with the path of "-", it claims
ownership of the stdout file descriptor. This means that it closes
stdout when it is destroyed. If there are multiple users of
raw_fd_ostream wrapped around stdout, then a crash can occur because
of operations on a closed stream.

An example of this would be running something like "clang -S -o - -MD
-MF - test.cpp". Alternatively, using outs() (which creates a local
version of raw_fd_stream to stdout) anywhere combined with such a
stream usage would cause the crash.

The fix duplicates the stdout file descriptor when used within
raw_fd_ostream, so that only that particular descriptor is closed when
the stream is destroyed.

Patch by James Henderson!

Zachary Turner 4a86af07a2 [Support] Improve flexibility of binary blob formatter.
This makes it possible to indent a binary blob by a certain
number of bytes, and also makes some things more idiomatic.
Finally, it integrates this binary blob formatter into ScopedPrinter
which used to have its own implementation of this algorithm.

Greg Clayton bde0a1632b Added the ability to dump hex bytes easily into a raw_ostream.
Unit tests were added to verify this functionality keeps working correctly.

Example output for raw hex bytes:
llvm::ArrayRef<uint8_t> Bytes = ...;
llvm::outs() << format_hex_bytes(Bytes);
554889e5 4881ec70 04000048 8d051002
00004c8d 05fd0100 004c8b0d d0020000

Example output for raw hex bytes with offsets:
llvm::outs() << format_hex_bytes(Bytes, 0x100000d10);
0x0000000100000d10: 554889e5 4881ec70 04000048 8d051002
0x0000000100000d20: 00004c8d 05fd0100 004c8b0d d0020000

Example output for raw hex bytes with ASCII with offsets:
llvm::outs() << format_hex_bytes_with_ascii(Bytes, 0x100000d10);
0x0000000100000d10: 554889e5 4881ec70 04000048 8d051002 |UH.?H.?p...H....|
0x0000000100000d20: 00004c8d 05fd0100 004c8b0d d0020000 |..L..?...L..?...|

The default groups bytes into 4 byte groups, but this can be changed to 1 byte:
llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 16 /*NumPerLine*/, 1 /*ByteGroupSize*/);
0x0000000100000d10: 55 48 89 e5 48 81 ec 70 04 00 00 48 8d 05 10 02
0x0000000100000d20: 00 00 4c 8d 05 fd 01 00 00 4c 8b 0d d0 02 00 00

llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 16 /*NumPerLine*/, 2 /*ByteGroupSize*/);
0x0000000100000d10: 5548 89e5 4881 ec70 0400 0048 8d05 1002
0x0000000100000d20: 0000 4c8d 05fd 0100 004c 8b0d d002 0000

llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 8 /*NumPerLine*/, 1 /*ByteGroupSize*/);
0x0000000100000d10: 55 48 89 e5 48 81 ec 70
0x0000000100000d18: 04 00 00 48 8d 05 10 02

Zachary Turner 39571b37a3 Teach raw_ostream to support hex formatting without a prefix '0x'.
Previously using format_hex() would always print a 0x prior to the
hex characters.  This allows this to be optional, so that one can
choose to print (e.g.) 255 as either 0xFF or just FF.

Nick Kledzik e648037449 [Support] Add type-safe alternative to llvm::format()
llvm::format() is somewhat unsafe. The compiler does not check that integer
parameter size matches the %x or %d size and it does not complain when a 
StringRef is passed for a %s.  And correctly using a StringRef with format() is  
ugly because you have to convert it to a std::string then call c_str().
 
The cases where llvm::format() is useful is controlling how numbers and
strings are printed, especially when you want fixed width output.  This
patch adds some new formatting functions to raw_streams to format numbers
and StringRefs in a type safe manner. Some examples:

   OS << format_hex(255, 6)        => "0x00ff"
   OS << format_hex(255, 4)        => "0xff"
   OS << format_decimal(0, 5)      => "    0"
   OS << format_decimal(255, 5)    => "  255"
   OS << right_justify(Str, 5)     => "  foo"
   OS << left_justify(Str, 5)      => "foo  "

- As best I can tell, we have eliminated all the code which used to require a
   larger buffer size.

Daniel Dunbar 47a309c5ca Fix off-by-one in llvm::Format::print.
- This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)
