      [torque] Add option for printing Torque IR · ad0e581c
      Seth Brenith authored 
      While working on the Torque compiler, I've sometimes found it difficult
to understand Torque's intermediate representation and how it
corresponds to the output. In this change, I propose adding a build flag
that instructs Torque to emit comments describing its IR, interspersed
in the generated code. This is particularly useful for seeing the stack
management instructions (Peek, Poke, and DeleteRange) which don't emit
any corresponding C++ code.

      [regexp] Remove Zone usage in runtime-regexp.cc · 42a7fe1d
      Jakob Gruber authored 
      .. to reduce memory overhead. Zones allocate a minimum segment size of
8KB, and the uses in runtime-regexp.cc are expected to need << that.

Two uses were replaced by SmallVectors:

* CompiledReplacement, parses string replacement patterns for
  optimized repeated use.
* Intermediate data structures in RegExpReplace.
