9b4ba34c68 Fix segfaults on allocation failure (#4)
Throw std::bad_alloc instead of returning nullptr from
ue2::AlignedAllocator. Allocators for STL containers are expected never
to return with an invalid pointer, and instead must throw on failure.
Violating this expectation can lead to invalid pointer dereferences.

23e5f06594 add new Literal API for pure literal expressions:
Design compile time api hs_compile_lit() and hs_compile_lit_multi()
to handle pure literal pattern sets. Corresponding option --literal-on
is added for hyperscan testing suites. Extended parameters and part of
flags are not supported for this api.
