Fix assembly directives for SHA data generation.
With ".align 8" placed after the symbolic label, the values end up being
placed at the wrong location, thus causing reads of 0 (unitialized) values.
Consider the following assembly code:
foo:
.align 8
.byte 0x1
bar:
.align 8
.byte 0x2
baz:
.align 8
.byte 0x3
This will result in the following sample memory layout:
foo -> 0x400 (with value 1 there)
bar -> 0x401 (with value 0 - uninitialized memory)
0x408 (with value 2)
baz -> 0x409 (with value 0 - uninitialized memory)
0x410 (with value 3)
This patch moves the ".align 8" directive before each label.
