Add benchmark running on multiple flags.
Update size_tester to include cost of absl::GetFlag call.
Add size_tester invocation for bool flag.
New benchmark better represent GetFlag usage.

Avoid 64x64->128 multiplication in absl::Hash's mix on AArch64
On AArch64, calculating a 128-bit product is inefficient, because it requires a sequence of two instructions to calculate the upper and lower halves of the result. So calculate a 64-bit product instead.
Making MultType 64-bits means the upper 32 bits of the result do not participate in shift/xor, but the add/multiply gives us sufficient mixing.

Remove homegrown Round implementation
absl/time/duration.cc defined a Round implementation to accommodate old
versions of MSVC that lacked std::round(long double). Abseil no longer
supports those MSVCs, so we don’t need the homegrown implementation
anymore. Remove it, and replace calls to it with std::rint.

Move the Consume() conversion functions out of cord_rep_ring into cord_rep_consume.
This makes these functions generic, so we can repurpose these for the new Btree conversion functions.

Prefer `getentropy` for Emscripten.
It needs a different header, so I've separated it out from the GLIBC
check above.

Add BTREE tag for CordRepNode implementing a Btree cord.
This change only forward declared the CordRepBtree class (not implemented yet) and defines the enum value BTREE. While RING and BTREE should never co-exist, we define a new value for BTREE so as not to make transitioning between RING and BTREE harder than it needs to be. This changes shifts the FLAT value / computation from FLAT = 4 to FLAT =5
