We shouldn't impose those flags on people who use llvm-config for
building their own projects.

Linear scan regalloc is currently assuming that any register aliased with
a member of a regclass must also be in at least one regclass. That is not
always true. For example, for X86, RIP is in a regclass but IP is not.
If you're unlucky, this can cause a crash by invalidating the iterator.

When an operand class is defined with MIOperandInfo set to a list of
suboperands, the AsmMatcher has so far required that operand to also define
a custom ParserMatchClass, and InstAlias patterns have not been able to
set the individual suboperands separately. This patch removes both of those
restrictions. If a "compound" operand does not override the default
ParserMatchClass, then the AsmMatcher will now parse its suboperands
separately. If an InstAlias operand has the same class as the corresponding
compound operand, then it will be handled as before; but if that check fails,
TableGen will now try to match up a sequence of InstAlias operands with the
corresponding suboperands.

default implementation for x86, going through the stack in a similr
fashion to how the codegen implements BUILD_VECTOR. Eventually this
will get matched to VINSERTF128 if AVX is available.

implementation of EXTRACT_SUBVECTOR for x86, going through the stack
in a similr fashion to how the codegen implements BUILD_VECTOR.
Eventually this will get matched to VEXTRACTF128 if AVX is available.

operand being factorized (and erased) could occur several times in Ops,
resulting in freed memory being used when the next occurrence in Ops was
analyzed.

merge vector<intptr_t>::push_back() and vector<void*>::push_back() because
Enumerate() doesn't realize that "i64* null" and "i8** null" are equivalent.

doesn't return immediately after then the insert position in UniqueSCEVs will
be out of date. No test because this is a memory corruption issue. Fixes PR9051!

a few loops accordingly. Should be no functional change.
This is a step for more accurate cost/benefit analysis of devirt/inlining
bonuses.
