e9f40ae176 Remove double double words
I ran the thing below (piped to “grep -v namespace”), fixed things up,
and rewrapped comments in the affected file.

import re
import sys

LAST_WORD_RE = re.compile('^.*[\s]+([\w]+)$')
FIRST_WORD_RE = re.compile('^[^\w]+([\w]+).*$')

for path in sys.argv[1:]:
  with open(path) as file:
    line_number = 0
    last_word = None
    for line in file:
      line_number += 1
      first_word = FIRST_WORD_RE.match(line)
      if first_word and first_word.group(1) == last_word:
        print('%s:%u: %s' % (path, line_number - 1, last_word))
      last_word = LAST_WORD_RE.match(line)
      if last_word:
        last_word = last_word.group(1)

8c35d92ae4 Use the C++11-standardized alignof instead of ALIGNOF
Use the standard alignas instead of ALIGNAS in cases where this is
possible too. It’s not currently possible where ALIGNAS may be mixed
with other attributes, although the not-landed
https://codereview.chromium.org/2670873002/ suggests that where ALIGNAS
is mixed with __attribute__((packed)), it’s viable to write “struct
alignas(4) S { /* … */ } __attribute__((packed));”.

This includes an update of mini_chromium to

723e840a2f10 Remove ALIGNOF

546e64cd0b Centrally define CPUContextX86::Fsave and fsave↔︎fxsave conversions
As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.

test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.

Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

429a3368d4 win: Work towards getting 'minidump' to compile
- dbghelp.h requires windows.h to be included before it (ick!).
  Add a stub one for non_win to make this work.
- convert __attribute__ -> macro that can work work with MSVC;
- a handful of narrowing casts.

52c2f6edfc Add MinidumpContextWriter::CreateFromSnapshot(), everything downstream,
and its test.

Minidump context structures now interoperate more easily with snapshot
CPUContext structures, while maintaining identical layout to before.
This is facilitated by reusing the Fxsave types for the substructures
which were completely identical, and by using compatible logic to
initialize the minidump and snapshot structures for testing.

5906513e30 MinidumpContext: fix some problems in AMD64 (x86_64) context enums.
This fixes a sloppy compliation error: “Redefinition of enumerator
'kMinidumpContextX86Xstate'”. It also fixes CONTEXT_FULL, which should
contain floating-point registers but not segment registers unlike the
its 32-bit x86 equivalent.

Some comments are revised to provide better, um, context.

cb2288d174 Add MinidumpContext (X86 and AMD64 variants) and their writers.
These are fairly simple classes and it’s not valuable to test them
individually. They will be tested as part of MinidumpThreadWriter and
MinidumpExceptionWriter.
