      [base] Sync Optional implementation to chromium · da339e60
      Clemens Hammacher authored 
      There were a lot of tweaks and optimizations to chromium's
{base::Optional} implementation. This CL brings us back in sync with
that.
Some changes were needed to make this compatible with C++11 and with
GCC 4.8:
1) Types like std::decay_t and std::enable_if_t were rewritten to
   use std::decay and std::enable_if.
2) Some conditional no_except declarations were removed.
3) std::is_trivially_copy_constructible and
   std::is_trivially_move_constructible are assumed to be false on
   gcc 4 because it's unimplemented there.

      Warm up RNG when --random_seed is used · 88c5da04
      Alexei Filippov authored 
      The RNG state is initialized with random_seed parameter that usually
has lots of zeros. Each random generation iteration shuffles bits with
xor operation over the state. It takes a while before the state is populated
with enough 1s and starts generating uniformly distributed numbers.

The patch warms up the state with 32 iterations when --random_seed is used.

      [cleanup] Don't declare inline runtime functions by default · 49420760
      Peter Marshall authored 
      For each intrinsic/runtime function we define in runtime.h, an inline
version is automatically declared. We only ever use 24 of the inline
functions. Even though we don't call the other ones, macro magic means
they still take up space by existing in various arrays and tables like
kIntrinsicFunctions. They also create code in switch statements.

Some drive-by cleanups:
 - Remove the switch in NameForRuntimeId() and just use the table of
   runtime functions to lookup the name directly.
 - Remove tests for IsFunction, ClassOf and StringAdd intrinsics as
   they are the last users of the inline versions of these.
 - Remove the MaxSmi inline version as it is only used in tests.

Saves 64 KiB binary size.

      [base] Remove OffsetFrom and AddressFrom · 60d6f7c2
      Clemens Hammacher authored 
      Those two methods are spread over the code base, and their purpose is
often not clear. Historically, they were used to turn pointers into
integers in order to do computations on them. Today we have {Address}
which is uintptr_t, so we can compute directly on that.

This also makes the {RoundUp} and {RoundDown} macros only work on
integral values (including {Address}).
