[Ada] Infinite loop with concatenation and aspect
This patch fixes a bug where an array object initialized with a
concatenation, and that has an aspect_specification for Alignment,
causes the compiler goes into an infinite loop.

gcc/ada/
* exp_ch3.adb (Rewrite_As_Renaming): Return False if there are
any aspect specifications, because otherwise Insert_Actions
blows up.
gcc/testsuite/
* gnat.dg/concat3.adb: New testcase.
