Extends the current implementation of WASM exceptions to be able to throw exceptions with values (not just tags). An JS typed array (uint_16) is used to hold thrown values, so that the thrown values can be inspected in JS.

SetForceInlineFlag is now only used in tests. Earlier, it was also used in js builtins, because unless this flag was specified the js builtins were not inlined. All the performance critical js builtins are moved to turbofan builtins and SetForceInlineFlag is no longer used. We would like to remove this flag completely to simplify inlining heuristics. Also, this uses a bit on the SharedFuntionInfo.

For the HeapNumber case, use Float64Neg directly instead of a Float64Mul by -1.0. For the Smi case, logic is added to handle the boundary conditions (0 and Smi::kMinValue), and the general case is handled by a SmiSub from 0.

In the years since https://codereview.chromium.org/1331993004, a lot has changed in v8: Math.max/min are now CSA builtins, with lowerings in TF. In a quick test on my machine of the microbenchmark on that CL (modified with start and end values), I don't detect any difference in speed between the macro versions on master and this version.

We introduce an explicit LoweringResult data structure. Until this change, the lowering result could be recovered from the node. However, lowering monomorphic loads requires wiring different value and effect, so we need a structure that can express such lowering result.

Merge some stack operations to work on an even number of registers, adding a padding register where necessary. Some lightly-used macro assembler functions are inlined, to make pairing registers easier. Not all merges create an even number of register arguments yet. This is a step towards aligning the stack pointer to 16-bytes.

During JSTypedLowering, when we see a JSAdd where we know that at least one side is already a String, we can try to strength-reduce the other side to a string as well. And once we have that, check whether both sides are now String constants, and if the concatenation won't overflow the string length limit, we can just constant-fold the StringAdd. This improves the Six Speed template_string benchmarks by up to 5x, as we no longer need to perform the String concatenations on every loop iteration.

Linux builds have an include chain from src/perf-jit.cc: sys/mman.h -> bits/mman.h -> bits/mman-linux.h, which defines a MAP_TYPE macro that conflicts with InstanceType::MAP_TYPE in jumbo builds, for some jumbo_file_merge_limit values. Since MAP_TYPE isn't used in perf-jit.cc, it should be safe to #undef the macro immediately after the sys/mman.h #include statement.

This further reduces the amount of test-specific code. It will also help testing the wasm baseline compiler, since it is also being called from the {WasmCompilationUnit}. Also, move the {RuntimeExceptionSupport} flag from the {WasmFunctionCompiler} to the {TestingModuleBuilder}. There is no need to store this per function builder. The {TestingModuleBuilder} then passes it on to the {WasmCompilationUnit}, which finally sets it on the {WasmGraphBuilder}.
