If two functions require different features (e.g., `-mno-sse' vs. `-msse') then
we want to honor that, especially during LTO. We can do that by resetting the
subtarget's features depending upon the 'target-feature' attribute.

This simplifies selection of floating point loads/stores.

This dependency is for the testing of whether an instruction is a pseudo.

This is essentially a stripped-down version of the ConstandIslands pass (which
always had these two functions), providing just the features necessary for
correctness.
In particular there needs to be a way to resolve the situation where a
conditional branch's destination block ends up out of range.
This issue crops up when self-hosting for AArch64.

blocks. We still don't have consensus if we should try to change clang or
the standard, but llvm should work with compilers that implement the current
standard and mangle those functions.

This implements the review suggestion to simplify the AArch64 backend. If we
later discover that we *really* need the extra complexity of the
ConstantIslands pass for performance reasons it can be resurrected.

In the near future litpools will be in a different section, which means that
any access to them is at least two instructions. This makes the case for a
movz/movk pair (if total offset <= 32-bits) even more compelling.

assembler should also accept a two arg form, as the docuemntation specifies that
the first (destination) register is optional.
This patch uses TwoOperandAliasConstraint to add the two argument form.
It also fixes an 80-column formatting problem in:

1. Define and use function terminateSearch.
2. Use MachineBasicBlock::iterator instead of MachineBasicBlock::instr_iterator.
3. Delete the line which checks whether an instruction is a pseudo.

This patch doesn't introduce any functionality changes.
It adds some new fields to the Hexagon instruction classes and
changes their layout to support instruction encoding.

The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.
In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.
NOTE: This is a candidate for the Mesa stable branch.

If vector types have legal register classes, then LLVM bypasses LegalizeTypes
on them, which causes faults currently since the code to handle them isn't in

Since functions with internal linkage don't have language linkage, it is valid
to overload them:
extern "C" {
static int foo();
static int foo(int);
}
So we mangle them.
