   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:

7b8d8e9a54 [turbolizer] Use textContent to set code view
Previously code view was set using innerHTML. This would cause problems
for html characters in the code -- in particular, '<' without a space
after it would start new HTML tags, and the code following it wouldn't
be visible.

Now, the source text is set using textContent, which doesn't parse the
value as HTML and implicitly escapes any HTML characters in the code.

980448dfcd [Compiler] Remove CompileBaseline and three tier pipeline.
Since we no longer support the ignition-staging configuration 
any longer,  we can retire the three tier pipeline and the
CompileBaseline functionallity.

We still need support for JSFunction self healing due to
liveedit (which for --no-turbo might end up replacing a
forced Ignition function with a FCG function) - we can
remove this once we remove --no-turbo support.

ec1ffe39ed [tools] add lldbinit
The goal of this commit is to add the equivalent to gdbinit but
for lldb. I've tried to replicate the commands as close as possible
but I'm unsure about the jss command and hoping to get some feedback
on it in addition to the bta command which I'm not sure how/when this
could be used. This is probably just inexperience on my part.

The lldbinit file can be placed into a directory prefixed with dot
(.lldbinit) and the python script is currently expected to be in the
same directory. The path to the script can be changed manually if needed
as well.

8aa3459f20 [asm.js] Add stress mode for the asm.js validator.
This adds a --stress-validate-asm flag intended to stress test the
validator by running against every single function, independent of
whether a "use asm" directive is present. It mainly tests negative
cases because barely any function in our test corpus will be a valid
module according to the asm.js spec.

2ff2a0c65d tools: Add a script to generate arch-specific ctags

      $ tools/dev/gen-tags.py x64

  If no <arch> is given, it generates tags file for all arches:
      $ tools/dev/gen-tags.py

e7f5a04057 [tools] Standalone script for generating comparison of tools/run_perf.py results.
Inspired by bsuite/compare-baseline.py and tools/perf-to-html.py. The main difference
from the latter is that the new script does not require json files preprocessing and it
is able to compare multiple json files at once (just like bsuite/compare-baseline.py).

This CL also makes tools/run_perf.py relative path friendly.

0956e58792 [tools] Manually write JSON in profile.js to avoid huge strings
In the tick processor, in cases where there are a lot of ticks (e.g.
long running programs), JSON.stringify could throw a range exception
because the created string is too large.

Instead of creating the entire JSON string in memory, we now write the
top-level parts of the JSON manually, writing out the ticks individually
instead of all together.

118c376fcb [wasm] Initial signal handler
This is basically the minimum viable signal handler for Wasm bounds checks.
It includes the TLS check and the fine grained instructions checks. These
two checks provide most of the safety for the signal handler. Future CLs will
add code range and data range checks for more robustness.

The trap handling code and data structures are all in src/trap-handler, with
the code that actually runs in the signal handler confined to
src/trap-handler/signal-handler.cc.

This changes adds a new V8 API that the embedder should call from a signal
handler that will give V8 the chance to handle the fault first. For hosts that
do not want to implement their own signal handler, we include the option to
install a simple one. This simple handler is also used for the tests.

When a Wasm module is instantiated, information about each function is passed
to the trap handler, which is used to classify faults. These are removed during
the instance finalizer.

Several future enhancements are planned before turning this on by default.
Obviously, the additional checks will be added to MaybeHandleFault. We are
also planning to add a two-level CodeObjectData table that is grouped by
isolates to make cleanup easier and also reduce potential for contending on
a single data structure.
