Description

runtime: fix early GC of Defer objects go_bootstrap was panicking during runtime initialization (under runtime.main) because Defer objects were being prematurely GC'd. This happened because of an incorrect change to runtime·unrollgcprog_m to make it endian-agnostic during the conversion of runtime bitmaps to byte arrays.

[dev.power64] runtime: fix early GC of Defer objects

go_bootstrap was panicking during runtime initialization
(under runtime.main) because Defer objects were being
prematurely GC'd.  This happened because of an incorrect
change to runtime·unrollgcprog_m to make it endian-agnostic
during the conversion of runtime bitmaps to byte arrays.
