We require d/q suffixes on the memory form of these instructions to disambiguate the memory size.
We don't require it on the register forms, but need to support parsing both with and without it.
Previously we always printed the d/q suffix on the register forms, but it's redundant and
inconsistent with gcc and objdump.
After this patch we should support the d/q for parsing, but not print it when its unneeded.

This makes easier to identify changes in the instruction info flags. It also
helps spotting potential regressions similar to the one recently introduced at
r336728.
Using the same character to mark MayLoad/MayStore/HasSideEffects is problematic
for llvm-lit. When pattern matching substrings, llvm-lit consumes tabs and
spaces. A change in position of the flag marker may not trigger a test failure.
This patch only changes the character used for flag `hasSideEffects`. The reason
why I didn't touch other flags is because I want to avoid spamming the mailing
because of the massive diff due to the numerous tests affected by this change.
In future, each instruction flag should be associated with a different character
in the Instruction Info View.

Summary:
It's super irritating.
[properly configured] git client then complains about that double-newline,
and you have to use `--force` to ignore the warning, since even if you
fix it manually, it will be reintroduced the very next runtime :/

MOVNTPD/MOVNTPS should be WriteFStore
Standardized BDW/HSW/SKL/SKX WriteFStore/WriteVecStore - fixes some missed instregex patterns. (V)MASKMOVDQU was already using the default, its costs gets increased but is still nowhere near the real cost of that nasty instruction....
