r242414, for PR77881, introduces some bugs (PR78390, PR78438, PR78477).
It all has the same root cause: that patch makes combine convert every
lowpart subreg of a logical shift right to a zero_extract. This cannot
work at all if it is not a constant shift, and it has to be a bit more
careful exactly which bits it extracts.

From-SVN: r242757
Provide versions of subreg_lowpart_offset and subreg_highpart_offset
that work on mode sizes rather than modes. Also provide a routine
that converts an lsb position to a subreg offset.
The intent (in combination with later patches) is to move the
handling of the BYTES_BIG_ENDIAN != WORDS_BIG_ENDIAN case into
just two places, so that for other combinations we don't have
to split offsets into words and subwords.

The test fails for avr because fn1 does not get inlined into fn2. Inlining
occurs for x86_64 because fn1's computed size equals call_stmt_size. For the
avr, 32 bit memory moves are more expensive, and b[3] = p10[a] results in
a bigger size for fn1, preventing the inlining.
Add -finline-small-functions to force early inliner to inline fn1.
