Handle all 4 selects that wasm-compiler generates. Also modify unittest to allow optional operations (select operations are not supported on all archs).

Minor improvements for on heap reference vectors: - Use emplace_back instead of push_back. - Reserve initial capacity.

Port 732f394c Original Commit Message: StaGlobal didn't write the accumulator, but the baseline implementation assumed that it could preserve the accumulator by taking the return value of the StoreGlobalIC. This almost always worked, except for setters on the global object. Fix this by marking StaGlobal as clobbering the accumulator, same as StaNamedProperty (StaNamedProperty needs to do this anyway to avoid inlined setters from needing to create accumulator-preserving frames; StaGlobal would have needed the same thing if we'd ever inlined setters for it). Also, add a new debug scope, EnsureAccumulatorPreservedScope, to the baseline compiler, which checks if the accumulator value is preserved across non-accumulator-writing bytecodes. This found a (benign) bug with ForInPrepare, so fix that too.

1. Move Abspd, Negpd from MacroAssembler into TurboAssembler so that we can use it in code-generator 2. Add Absps and Negps (float32 versions of the instructions in 1) 3. Refactor SSE/AVX float32/float64 abs/neg to use these macro-assembler helpers. 4. Use these helpers in Liftoff too This has the benefit of not requiring to set up the masks in a temporary register, and loading the constants via an ExternalReference instead. It does require (in ins-sel) to have the input be in a Register, since the ExternalReference is an operand (and the instruction can only have 1 operand input).

Also move Pshufb definition into shared-macro-assembler. We define a Pshufb that handles both SSE and AVX, and in SSE case will move src to dst if they are not the same. Define operator== and operator!= in ia32's Operand class that will check against XMMRegister, we can then use DCHECK_NE to ensure that a register doesn't alias a operand wrapping a register.

This CL introduces a d8-only flag --expose-fast-api which enables the test FastCAPI object if the --turbo-fast-api-calls flag is enabled. It also disables --stress-snapshot, which is incompatible with fast calls.

This reverts commit 810d34df. Reason for revert: The stricter host checks prevent certain security issues. We will have to live with regressions until we have a more flexible caching solution in place.

The array buffer sweeper has its own freed counter which is migrated back to a global counter. There exist two paths for finalizing array buffer sweeping which both need to merge back the counters. If we miss out on merging back the counter, the freed counter may overflow in the next cycle.

This CL implements early SyntaxErrors for regular expressions. Early errors are thrown when a malformed pattern is parsed, rather than when the code first runs. We do this by having the JS parser call into the regexp parser when a regexp pattern is found. Regexps are expected to be relatively rare, small, and cheap to parse - that's why we currently accept that the regexp parser does unnecessary work (e.g. creating the AST structures). If needed, we can optimize in the future. Ideas: - Split up the regexp parser to avoid useless work for syntax validation. - Preserve parser results to avoid reparsing later.
