  This improves for-in by ~10% on non-initialized enum-caches

This CL prepares the way for adding a root register on ia32. The new
register allocation configuration PreserveRootIA32 treats
kRootRegister as an unallocatable register.

Note that kRootRegister (on ia32) is still completely unused,
unallocated, and may be clobbered at many points. This is left to
future work.

NeedsSourcePositionsForProfiling is used to control the generation of
the line end table during parsing (see ParseInfo::CreateScript). This
is costly both for memory and performance. Turning on detailed_line_info
by default caused regressions because we always generate the line end
table.

This CL splits the two conditions apart as they aren't related.

This may result in a minor asm.js scanning regression due to one-byte tokens

The CheckedInt32Mod lowering in the EffectControlLinearizer wasn't
playing well with subsequent optimizations in the MachineOperatorReducer
especially due to the use of Int32Mod, which introduces another (floating)
diamond in the MachineOperatorReducer. Switching to Uint32Mod and explicit
sign handling fixes the problem, plus we also do the mask trick in the
case where the left hand side is negative now.

With this change the performance on the benchmark mentioned in the bug
report goes from

  console.timeEnd: binary, 1872.346000
  console.timeEnd: modulo, 5967.464000
  console.timeEnd: binary, 6006.789000

  console.timeEnd: binary, 5969.264000

  console.timeEnd: binary, 5958.221000

The RegExp replace implementation is a bit of a mess. Here, we first
try to handle parts of RegExp.p.exec, and then call directly into the
raw irregexp code (skipping RegExp.p.exec).

We got parts of this wrong: when lastIndex > string.length and the
regexp instance is sticky, two things should happen. 1. The match
should fail, and 2. lastIndex should be reset to 0. On the fast path,
we did the latter but not the former, instead running exec with a
lastIndex of 0.

This CL omits the irregexp call in this case, and defaults to a failed
match instead.
