Crashes are still happening despite tentative fixes, but unfortunately
without a local repro. This adds a couple of additional checks to help
flush out the root cause.

TryCatch only clears the pending exception if it has been propagated
through OptionalRescheduleException. This is another tentative fix for
https://crbug.com/754422.

With this CL the regexp-parser-fuzzer uses the first byte of the fuzzer
input to select the regexp flag instead of executing each input with all
possible flags. Thereby the fuzzer can explore more inputs and with its
coverage metric will explore all flags only for interesting inputs.
I updated all files in test/fuzzer/regexp and added a random byte at the beginning. This byte is used by the fuzzer to determine the flag.

Now that all accesses to the last match info are in C++ and TF code, we can
finally turn the last match info into a FixedArray. Similar to the ArrayList,
it uses its first field to store its length and grows dynamically in amortized
O(1) time.
Unlike previously, this means that the last match info pointer stored on the
context can actually change (in case the FixedArray needs to grow).

Thrown exceptions must be handled before another exception is thrown.
This fixes all remaining test failures exposed by not clearing pending
exceptions in JSEntryStub.
