Since we naively build the JS source code through concatenation,
we need to ensure the regexp literal does not end up being interpreted

As part of https://chromium-review.googlesource.com/902283 I changed the
JSCreateClosure lowering to respect the pretenure flag on the operator,
but that tanks some benchmarks heavily, as the Parser marks closures
like
args[l] = function(...) { ... }
for old-space allocation, which backfires for short-living closures.

Timeouts on num-fuzzer only lead to false positives, as tests might

This CL forgives timeouts through a global override mechanism of the

Original Commit Message:
We reuse most of the infrastructure to set break points, with minor
differences when we encounter functions where we can only break on entry:
- PrepareFunctionForBreakPoints simply deopts all functions.
- Break point objects have the canonical source position 0.
- Break point is set/checked/cleared via bit on the DebugInfo.
- Debug::Break do not continue stepping since stepping is implemented via
regular break points and therefore do not interfere with break on entry.
I promise to add more tests.

PromiseHooks can be called with a proxy which fails the cast and
crashes. This patch changes the runtime functions to
explicitly check for a JSPromise.
This has the side effect of removing the existing broken support for

For local variables of type i64 and also for i64 constants, it makes
sense to store the constant value in the {VarState} instead of loading
the value into a register immediately. This also helps with some
instructions like i64 bitshifts, but also general patterns like
incrementing an i64 local variable by a fixed number.
