VASM part 2: call, shuffleArgs, shuffle2, syncpoint, vregs

Summary: Converts more emitter-helper code to use VASM, notably shuffleArgs,
prepXMM, and PhysRegSaver. Start using makeReg() to generate temporary
virtual registers instead of named reserved tmps like rAsm/rCgGP/rCgXMM*.

VASM part 3: calls and other trickyness

Summary: Convert cgCallHelper to vasm. The two interesting parts of this are
catch edges and LdObjMethod. LdObjMethod requires two special vasm
opcodes that support the alignment and patching that goes on.

Catch blocks are supported by an "unwind" instruction that behaves like
a conditional branch; the taken edge represents a transfer of control
from the callee to the unwinder block. The normal edge represents a
normal return.

This diff starts using vasm for service requests. the service request
opcodes encapsulate more or less all of the corresponding emitReqXXX
helper functions, so they generate more asm after register allocation
and sometimes re-enter Vauto recursively. See t4785959.

VASM part 4: hoist vasm up to cgInst

Summary: Hoist the creation of the main assembler to cgInst; at this point,
each CodeGenerator cg* function must be fully converted to vasm or
left alone (fully x64-asm).

VASM part 5: decrefs, cgBinaryIntOp, cgBinaryDblOp, less m_rScratch

Summary: Converted the decref family of functions. Instead of emitting code
with an unpatched forward jump, and patching it later, the vasm version
creates the "done" block early, and passes it down to the various decref
helpers as the target to use if there's no decrement needed. (cleaner).

Converted cgCallNative so all CALL_OPCODE opcodes are converted.
vasm-ified cgBinaryIntOp and cgBinaryDblOp, and simplified them somewhat
by de-inlining special cases (noncommutative or overflow-detecting).
(these look more complicated now, but get simpler again in patches
higher in the stack).

Force hhi root to be set in master before workers fork

Summary: Make sure that the workers all get the same, preset hhi path,
computed by the master before they fork. This could manifest as a worker
trying to re-extract the hhi files to a preexisting location (since the
random seed is shared across all of them) and hitting an exception when
the directory already exists.

It's pretty weird that we didn't run into this immediately when I did
the hhi embedding -- AFAICT this has been wrong since day one. I think
what saved us is the logic that says "if the number of changes is lower
than N, do it all in the master", where N is about 10 -- so most of the
time this didn't matter. (And it looks like during init we do some other
stuff in the master too or something? In any event, this was hard to
trigger.)
