Modify V8 histograms by adding asm/wasm suffices.

Modify V8 histograms by adding asm/wasm suffices.

Do final change to chrome histogram flags so that V8 UMA will start collecting separate statistics for asm.js and WASM modules.

This is being done because asm.js and WASM modules have different
semantics and size expectations, making it very hard to tell what are
asm.js issues and what are WASM module issues. To fix this, adding
suffixes "asm" and "wasm" to current histograms.

Code for V8 has already been modified to collect separately, except
for histogram table names. This fianl fix for histogram table names
can be found in:
