fe1040f Drop -Wno-shift-count-overflow compile flag (Pieter Wuille) 154bcd4 Avoid >> above type width in BitWriter (Pieter Wuille) Pull request description: For tiny fields (bits <= 8), the table type is `uint8_t`, which results in `BitWriter` using uint8_t logic as well. This is technically UB, as it performs right shifts of up to 8 positions. Avoid this by performing the BitWriter logic in either the table type, or `unsigned`, whichever is larger. This is an alternative to #71. ACKs for top commit: hebasto: re-ACK fe1040f. Only rebased since my [recent](#74 (review)) review.

Instead of disabling a compiler warning for the entire codebase, it is safer to disable it for a single line of code.
