- This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution.

not unrolling loops that contain calls that would be better off getting inlined. This mostly
comes up when an interleaved devirtualization pass has devirtualized a call which the inliner
will inline on a future pass. Thus, rather than blocking all loops containing calls, add
a metric for "inline candidate calls" and block loops containing those instead.

instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.
This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use
all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific.
No intended functionality change.

- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

of checking for either 4 or 8 is not very satisfactory, but
it would catch the original problem (an alignment of 1).

removed. Not that the XTARGET wasn't doing anything since it
does nothing without an accompanying XFAIL.

the VST pseudos. The VLD/VST scheduling still needs work (see pr6722), but
at least we shouldn't confuse the loads with the stores.

This will preserve any other flags (e.g., kill) on the operand.

to materialize easy constants if we can.

For VLD3/VLD4 with double-spaced registers, add the implicit use of the
super register for both the instruction loading the even registers and the
instruction loading the odd registers.

unrolling threshold to the optimize-for-size threshold. Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.
