f106e4266a Enable the IL verifier by default. 
Change the default value for the "enable_verifier" setting so the
verifier runs unless it is explicitly disabled.

Most projects using Cretonne are best off running the verifier always
until they start caring about compile time performance. Then they can
easily disable the verifier.

c09ad06f96 Stop generating reserved_reg heaps in DummyEnvironment. 
The reserved register heaps are not implemented in the Cretonne
legalizer, so IR generated by the dummy environment would trip
assertions when compiled.

Use a heap with a vmctx base address instead, and also demonstrate how
vmctx arguments are added to all signatures to achieve this.

b8fe6bf0f5 Add a MapCursor::value_mut() method. 
It's ok to alter a value stored in a map, but not the keys.

b049916d35 Move %rsp to %rbp, not the reverse. 
This also takes away %rsp and %rbp from regalloc again. This may cause
tests to fail temporarily.

27f0b29188 Replace hex with "0x%x" % ... to fix a trailing 'L' on 32-bit python2 
This test was failing because the hash computes values greater than
0x7fffffff, which 32-bit python2 promotes to long, which `hex` formats
with a trailing 'L'. The code that uses it appears to be ok with a
long value, so it's just the test that needs to handle it.

Fix as suggested here:
