df926ef62f Implement new Vermicelli16 acceleration functions using SVE2. 
The scheme utilises the MATCH and NMATCH instructions to
scan for 16 characters at the same rate as vermicelli
scans for one.

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.

86c5f7feb1 FDR: Squash buckets of included literals in FDR confirm 
- Change the compile of literal matchers to two passes.
 - Reverse the bucket assignment in FDR, bucket with longer literals has
   smaller bucket id.
 - Squash the buckets of included literals and jump to the the program of
   included literals directly from parent literal program without going
   through FDR confirm for included iterals.

221229f71c gcc7: comments for falling through a switch case 
GCC 7 adds a warning -Wimplicit-fallthrough to catch when falling
through a switch statement without a break. Since we actually want that
behaviour sometimes, we can add a comment so the compiler knows we
intended the fallthrough.
