c29a56dedb Fix PR3241: Currently EmitCopyFromReg emits a copy from the physical register to a virtual register unless it requires an expensive cross class copy. That means we are only treating "expensive to copy" register dependency as physical register dependency. 
Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet.

255b26ea35 simplify CallSite helper class to not consult the Instruction's 
opcode on each delegation.
Instead the information is cached on construction and the cached flag used thereafter.
Introduced two predicates: isCall and isInvoke.

4362387c74 Do not inline functions with (dynamic) alloca into 
functions that don't already have a (dynamic) alloca.
Dynamic allocas cause inefficient codegen and we shouldn't
propagate this (behavior follows gcc).  Two existing tests
assumed such inlining would be done; they are hacked by
adding an alloca in the caller, preserving the point of
the tests.

38593664b0 * Don't explicitly cast "0" to "void*". This doesn't work well with specialized 
StringMapEntryInitializer classes. Leave it for the compiler to figure out what
 the type is and what "0" should be transformed into.

* Un-disable the unit tests which test the StringMapEntryInitializer class.

8f90b6eb2f The coalescer does not coalesce a virtual register to a physical register if any of the physical register's sub-register live intervals overlaps with the virtual register. This is overly conservative. It prevents a extract_subreg from being coalesced away: 
v1024 = EDI  // not killed
      =
      = EDI

One possible solution is for the coalescer to examine the sub-register live intervals in the same manner as the physical register. Another possibility is to examine defs and uses (when needed) of sub-registers. Both solutions are too expensive. For now, look for "short virtual intervals" and scan instructions to look for conflict instead.

This is a small win on x86-64. e.g. It shaves 403.gcc by ~80 instructions.
