Nico Hartmann 362e265d4c Revert "[Torque] Generalize Torque literals to larger size" 
This reverts commit 757830b02b.

Reason for revert: Speculatively revert due to a number of
performance regressions

Original change's description:
> [Torque] Generalize Torque literals to larger size
>
> Previously, literals in Torque were stored as double values, which
> made it impossible to precisely represent 64 bit integer values.
> This CL replaces the old literal expression with an integer and
> floating point literal expression that are unbounded in size. We
> allow implicit conversion of these literals to arbitary integer
> and floating point types respectively and insert a corresponding
> bounds check into generated CSA.

V8 debug helper

This library is for debugging V8 itself, not debugging JavaScript running within V8. It is designed to be called from a debugger extension running within a native debugger such as WinDbg or LLDB. It can be used on live processes or crash dumps, and cannot assume that all memory is available in a dump.
