Martin Storsjö e75a0f3c75 checkasm: aacencdsp: Actually test nonzero values in quant_bands 
Previously, we read elements from ff_aac_pow34sf_tab; however
that table is initialized to zero; one needs to call
ff_aac_float_common_init() to make sure that the table is
initialized.

However, given the range of the input values, a large number of
entries in ff_aac_pow34sf_tab would give results outside of the
range for signed 32 bit integers. As the largest aac_cb_maxval
entry is 16, it seems more reasonable to produce values within
an order of mangitude of that value.

(When hitting INT_MIN, implementations may end up with different
results depending on whether the value is negated as a float or
as an int. This corner case is irrelevant in practice as this
is way outside of the expected value range here.)

Coincidentally, this fixes linking checkasm with Apple's older
linker. (In Xcode 15, Apple switched to a new linker. The one in
older toolchains seems to have a bug where it won't figure out to
load object files from a static library, if the only symbol
referenced in the object file is a "common" symbol, i.e. one for
a zero-initialized variable. This issue can also be reproduced with
newer Apple toolchains by passing -Wl,-ld_classic to the linker.)
