c692cb77aa Match VTRN, VZIP, and VUZP shuffles. Restore the tests for these operations,
now using shuffles instead of intrinsics.

9085750d31 Try again at privatizing the layout info map, with a rewritten patch.
This preserves the existing behavior much more closely than my previous attempt.

eb01abaad1 Implement support for ISRs.
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

5cfd4ddece PowerPC inline asm was emitting two output operands
for a single "m" constraint; this is wrong because the
opcode of a load or store would have to change in parallel.
This patch makes it always compute addresses into a register,
which is correct but not as efficient as possible.  7144566.
