1. "no 'else' after 'return'" -- this is for conformance with the
coding standards.

2. move 'else' to the line of the previous '}' -- this is for consistency.

Refactor the ELFRelocationEntry (pull up) and move the arch-specific statics to inside the class where it belongs.

Next step is to rationally break apart the RecordRelocation()

Probably the step will be to have 1 member function for ech slot of the ELFRelocationEntry()

state. Previously Thumb2 would restore sp from fp like this:
mov sp, r7
sub, sp, #4
If an interrupt is taken after the 'mov' but before the 'sub', callee-saved
registers might be clobbered by the interrupt handler. Instead, try
restoring directly from sp:
add sp, #4
Or, if necessary (with VLA, etc.) use a scratch register to compute sp and
then restore it:
sub.w r4, r7, #8
mov sp, r7

stdlib.h. There were numerous problems with forward declaring 'malloc' and
'free', but the most important is that these are reserved by POSIX and may be
implemented via a function-like macro.

As suggested by Dale Johannesen, I'm instead guarding the only include of this
in our builtin headers with __STDC_HOSTED__, and I've removed the include of
the header from the test suite. I'll discuss with folks whether we want to have
a hosted section of the test suite or not, and add it (and perhaps other tests)
back there if that's the direction.
