This adds a new profiling mode for vector instruction
shapes. I'm planning on using this to identify any common cases that
may be worth special casing, like we do for simple SetM, CGetM, and
IssetM instructions. Instead of adding Yet Another Hashtable Stats
Map, I created a generic version and changed TRACE=punt:1 to use it as
well.
I also changed emitInterpOneOrPunt to use a more specific name.
g++-4.7.1 treats "FOO"bar as a c++-11 literal operator, even
if bar is a macro with an expansion such as "BAR" - so add a space
after the quote (this seems like a bug, and I fixed a bunch of these
a while ago, but we just added a slew of PRI*64 macros which break
under 4.7.1).
Also, it warned that "explicit by-copy capture of 'this' redundant"
for a lambda declared [=, this] - so I removed the this.
We also needed more than the 60 levels of template expansion that was
allowed by the makefile.
Per @mwilliams' suggestion, this is the first stage in a staggered approach to replacing int64 with int64_t. More precisely I inserted "typedef ::int64_t int64;" in util/base.h and dealt with the consequences.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
