Subject: Mark SoftwareSerial::tx_pin_write as "always_inline"

Somehow gcc 4.8 doesn't inline this function, even though it is always
called with constant arguments and can be reduced to just a few
instructions when inlined. Adding the always_inline attribute makes gcc
inline it, saving 46 bytes on the Arduino uno.

gcc 4.3 already inlined this function, so there are no space
savings there.
