Subject: [PATCH] Update aspirational_scripts per Unicode 9

This is a preparation to update ICU to 58.1.
Without this change, ICU update CL cannot be tested on
trybots because a compile will fail due to '#error' checking
if ICU version is less than 58.

BUG=637001
TEST=None

Subject: [PATCH] Prepare to upgrade ICU to 58 part 2

U_LB_COUNT is assumed to be 40 in Blink line breaking code, but it's
43 in ICU 58/Unicode 9.

Three new classes (Emoji Base, Emoji Modifier, and ZWJ) should behave
identically whether or not 'word-break: break-all' is in effect.

BUG=637001
TEST=TextBreakIterator.cpp is compiled without an error with ICU 58.
