c63c073d27 Do IWYU for check_op.h
Include check_op.h directly, instead of relying on the transitive
include from logging.h. This transitive include does not exist in
Chromium's //base.

dcdccf56f2 [fuchsia][arm64] Don't query for fp registers
Fuchsia devices are failing to read floating point context for ARM
because floating point registers are in the vector context for ARM.

This CL prevents warning logs from being emitted in this situation.

0208c1a175 fuchsia: Don't capture incorrect/unreasonably large stacks
In a stack overflow test from the Fuchsia tree, an intentional crash was
being induced that at the point it was reported to Crashpad resulted in
a stack pointer outside of the stack. This caused two problems:

- Crashpad attempted to capture that whole "thing" which could have been
  anything, and in the failing test was a 1G guard region
- The whole wrong thing could be very large, resulting in OOM when
  trying to write the minidump, which was the symptom of the bug.

Don't attempt to continue of SP isn't at least in a mapping, and don't
capture too-large regions for the stack as nothing useful can come of
that anyway.

New test added: ProcessSnapshotFuchsiaTest.InvalidStackPointer.

b71f61f8e3 fuchsia: Defer initialization of memory map
This allows partial reading of the current process (e.g. modules or
CrashpadInfo), even though the memory map read (and so thread retrieval)
will fail if ProcessSnapshotFuchsia is used on the current process.

This is a follow up to
db6f51d3fc
which broke the CrashpadInfoClientOptions.* tests.

db6f51d3fc fuchsia: Check results of Initialize() subcalls in ProcessReaderFuchsia
From looking at some syzkaller logs, the earliest error seems to be

  [...ERROR memory_map_fuchsia.cc:47] zx_object_get_info ZX_INFO_PROCESS_MAPS: ZX_ERR_BAD_STATE (-20)

which might be caused by a failure to suspend. That error causes
ProcessReaderFuchsia's memory_map_ Initialize() to fail, but that was
mistakenly being ignored. Later calls then fail as well.

While we're here, also check a couple other Initialize()s that were
sometimes triggering later on.

efaebfc482 fuchsia: Capture from SP (+slop) to stack base, rather than entire stack
Stack mappings can be enormous for some processes dwarfing all other
data and making the .dmp useless. It isn't useful to capture beyond the
stack pointer, so grab only from the stack base to the stack pointer.

In the default config (safestack enabled), this isn't a major problem.
However, Chromium has safestack disabled, along with a large stack size,
so dumps with many threads become very large.

b0373799ba [fuchsia] fix module names for executables and loadable modules
On Fuchsia, executables and loadable modules don't have a name at build
time so we use "<_>" as module name to index their symbols on the crash
server. We need to use the same dummy value at run time.

bce68d7975 fuchsia: Miscellaneous fixes to get symbol resolution working
- Endian-swaps the 3 integer fields of the build id when returning it
  for use as the module id (see bug 229).
- Removes the "app:" prefix on the main binary, as this prevents the
  crash server from matching the binary name (and it isn't particularly
  useful anyway)
- Map "<vDSO>" to "libzircon.so" as that's what it actually is, so that
  symbols for it can be found.
