Fix bogus failure of uninit-19.c for avr

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.

runtime: rewrite panic/defer code from C to Go

    The actual stack unwind code is still in C, but the rest of the code,
    notably all the memory allocation, is now in Go.  The names are changed
    to the names used in the Go 1.7 runtime, but the code is necessarily
    somewhat different.

    The __go_makefunc_can_recover function is dropped, as the uses of it
    were removed in https://golang.org/cl/198770044.
