Eliot Miranda uploaded a new version of Compiler to project The Trunk:

==================== Summary ====================

Name: Compiler-eem.339
Author: eem
Time: 3 April 2017, 4:41:32.232382 pm
UUID: fc3a8d3e-45e0-4d89-adde-ae01ce361263
Ancestors: Compiler-eem.338

Have the Parser obey the bytecode set preference in CompiledCode preferredBytecodeSetEncoderClass.  Fix a restriction in BytecodeEncoder>>computeMethodHeaderForNumArgs:numTemps:numLits:primitive: that caused EToys to have to implement an unnecessary override.
Fix the literal limit in that same method.  The max number of literals is 32767 now that we reserve bit 15 for the "do not jit-compile with counters' bit in Sista VMs.
