Recent changes to the wasm format prevent you from knowing
the function index of a direct call until you know how many
imports you have (the index spaces have been merged).

Asm.js validation can't know this until all callsites have been
visited if you want to avoid materializing the entire AST / parsing twice.
Instead, keep a list of fixups to perform for all direct callsites,
then update these with the imports count added when emitting the module.

Currently the parameter is first parsed as a reference, and then translated into a parameter. The reference stays around though, and gets resolved to the parameter. That automatically creates a use. Now that I drop all unresolved references when we abort preparsing, that also drops the unresolved reference.

Instead, mark the variable as used when its marked as forced context allocation. That's what happens in almost all other cases.

This raises the question: does it really make sense to parse parameters this ways? It seems pretty generic, but neither fast nor memory-efficient ... Did I misunderstand something?

Just land if you think the CL looks good as is.

Re-enable marking functions for optimized compilation on the next call
when using OSR. We would previously do this for all functions. However,
it only benefits functions marked for concurrent recompilation. These
would potentially run unoptimized again and be OSRed again.
In addition any function that already was optimized concurrently had
it's optimized code removed and would have been recompiled. Functions to
be baselined would skip that and possibly deopt.

Hashmaps with a simple key equality method (comparing pointers) don't
need to waste cycles (and branches) comparing hash values, as the key
comparison is cheap.

This patch modifies the hashmap's MatchFun to take the hashes as well as
the keys, thus allowing the MatchFun to ignore the hashes. This allows
slightly cleaner generated code, especially when the MatchFun is
inlined.

There are only a few occasions where we allocate a register in an outer
expression allocation scope, which makes the costly free-list approach
of the BytecodeRegisterAllocator unecessary. This CL replaces all
occurrences with moves to the accumulator and stores to a register
allocated in the correct scope. By doing this, we can simplify the
BytecodeRegisterAllocator to be a simple bump-pointer allocator
with registers released in the same order as allocated.

The following changes are also made:
 - Make BytecodeRegisterOptimizer able to use registers which have been
   unallocated, but not yet reused
 - Remove RegisterExpressionResultScope and rename
   AccumulatorExpressionResultScope to ValueExpressionResultScope
 - Introduce RegisterList to represent consecutive register
   allocations, and use this for operands to call bytecodes.

By avoiding the free-list handling, this gives another couple of
percent on CodeLoad.
