Move extern declarations for _sqlite3_*_blocking functions before
_sqlite3_exec_no_args which references them. Remove unused
_sqlite3_prepare_v2_nolen function.
- Add _sqlite3_exec_no_args() C function that combines prepare+step+finalize
into a single CGO crossing for parameterless exec (most common case)
- Add _sqlite3_reset_clear() C function that combines sqlite3_reset and
sqlite3_clear_bindings into a single CGO crossing
- Use semaphore channel instead of result struct channel in context-aware
exec/Next paths to reduce allocations
- Use time.AppendFormat with stack buffer to avoid heap allocation in
time.Time binding
- Optimize bindNamedIndices to reuse a single buffer instead of 3
separate C.CString allocations
- Remove intermediate bindIndices slice allocation in named parameter
binding path
- Pass explicit query length to sqlite3_prepare_v2 to avoid C-side strlen
benchstat (n=8):
BenchmarkExec: -29.44% sec/op, -50% B/op, -33% allocs/op
BenchmarkQuery: -9.83% sec/op
BenchmarkParams: -6.38% sec/op
geomean: -6.72% sec/op
- Replace len(args[start:start+na]) > 0 with na > 0 to avoid slice bounds check
- Use range loops instead of manual index loops for cols/decltype slices
- Use range variable v.Ordinal instead of re-indexing args[i].Ordinal
- Add bounds hint for decltype access in nextSyncLocked loop
* Add ability to set an int64 file control
* Update documentation
* Remove duplicate err check in test
* Update sqlite3.go

GCP (at least Google Compute Engine) is a VM, and does not have restrictions relating to gcc.
Also it appears that this whole section refers to general compiling, rather than compiling on GCP.
