Fix a couple issues where we didn't correctly delay diagnostics in PotentiallyPotentiallyEvaluated contexts.  In preparation for making sizeof() PotentiallyPotentiallyEvaluated.

Load/store instructions w/ a fixup to be relative a function marked as thumb
don't use the low bit to specify thumb vs. non-thumb like interworking
branches do, so don't set it when dealing with those fixups.

When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.

The JIT is expected to take ownership of the TM that's passed in. The MCJIT
wasn't freeing it, resulting in leaks.

Auto deduction support for std::initializer_list, including for-range support. This means you can now write:

There are 5 functions of this name in Sema, and 6 more static helpers in
SemaTemplateDeduction.cpp. The Sema functions have jobs like "deduce for
function call", "deduce for taking the address", etc. The static helpers
have jobs like "deduce by comparing two types", "deduce by comparing two
lists of types", "deduce by comparing two template arguments", etc.
The fact that they all are called the same and only differ in two of their
6 or more arguments makes the code using them very hard to read.

Here I rename the one function that concerns me most at the moment, but
as a matter of cleanup, the others will eventually be renamed as well.

Add a trivial implementation of the getCallPreservedMask() hook.

Targets can now add CalleeSavedRegs defs to their *CallingConv.td file.
TableGen will use this to create a *_SaveList array suitable for
returning from getCalleeSavedRegs() as well as a *_RegMask bit mask
suitable for returning from getCallPreservedMask().

When the non-local symbol in the expression is in the same fragment
as the second symbol, the assembler can still evaluate the expression
without needing a relocation.

For example, on ARM:
_foo:
	ldr lr, (_foo - 4)
