This CL adds support to parse a PushStackTraceAndDie dump on a windows
minidump:
Stack Message:
magic1: 00000000bbbbbbbb
magic2: 00000000bbbbbbbb
ptr1: 00000015f9ca78d1 T
ptr2: 0000000000000000
message start: 00000000002c58f0 S
stack_start: 00000000002cd8f0 S
All addresses within the message are annotated with the address marker to
make it easier to spot objects that are contained in the minidump.
Currently this doesn't work on OSX yet as we do not correctly push the two
magic markers on the stack.

- Add new address markers:
T: tagged pointer in the minidump
C: address into a module in the minidump
S: pointer into the exception stack in the minidump
*: other address in the minidump
- Show ASCII decoding of address in dd
- Display potential frame markers on the exception stack:
00000032212fdae8: 0000000300000000 ........ Smi(3) EXIT frame marker
- Display relative addresses, useful to detect stack frames:
00000032212fdb68: 00000032212fdb98 S ........ [+6]=00000032212fdcb0 S
00000032212fdb70: 0000010ff5ca0a84 ........

- support register expression for addresses, e.g.: $r15-1
- show whether addresses are in the minidump with "*"
- show decoded Smis with dd
- dd without arguments continues printing the next words

Minidumps have gotten bigger stack ranges leading to long load times when using
grokdump's web interface. A major factor seems to be the output size of the
generated table. Using shorter class names and avoiding quotes for most
attributes we can get a significant size reduction.

This is a prototype to start discussion about useful features for
a better/friendlier minidump analysis tool.
The change adds an -w option to grokdump.py. With the option on,
grokdump will launch a web server and web browser for browsing the
minidump. It also supports adding persistent comments and listing +
browsing other minidumps (in the same directory) without the need to
restart the web server.

Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.
External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.
Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.
Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned

In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.
The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.
Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.
