      Revert of Decompiler improvements. (patchset #2 id:20001 of https://codereview.chromium.org/1177123002/)

Reason for revert:
Code printout has become unreadable. Offsets are printed in decimal numbers everywhere else. This is inconsistent with the rest of the code-base. Some examples are tables for deoptimization data, safepoints and exception handlers. I would be fine with this change if _all_ tracing would be adapted. But there are _many_ places to touch.

      The main motivation is simplifying profiling activities:

1) Use hex instead of decimal for offsets, just like perf does. This
affects --print-opt-code

2) When printing block information, indicate loop information: if
block is header, where the end is; if block is in a loop, where the
loop starts. This affects --code-comments.

Using --print-opt-code --code-comments, and cross-referencing with data
obtained from perf, one may now find the block a hotspot belongs to
without needing to do hex2dec/dec2hex conversions. Once found, loop info
is available locally, on the block.

      Serializer: simplify external reference encoding. · a8e82da6
      yangguo authored 
      External references are encoded as a tuple of type and ID. This
requires both the external reference encode and the decoder to
create a mapping between the encoding and the external reference
table index.

Instead, we simply use the external reference table index as
encoding.

We now also assume that there are no duplicate entries. Existing
duplicates have been removed in this change.

      1) The hardcoded strings were converted into DeoptReason enum.

2) Deopt comment were converted into a pair location and deopt reason entries so
the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.

3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.
