Testsuite: Add missing 'torture-init'/'torture-finish' around 'LTO_TO…

…RTURE_OPTIONS' usage

Recent commit d6654a4
"Let each 'lto_init' determine the default 'LTO_OPTIONS', and 'torture-init' the 'LTO_TORTURE_OPTIONS'"
made it a requirement that 'LTO_TORTURE_OPTIONS' usage be within
'torture-init'/'torture-finish', and missed a few cases that didn't have that.

	gcc/testsuite/
	* gcc.target/arm/acle/acle.exp: Add missing
	'torture-init'/'torture-finish' around 'LTO_TORTURE_OPTIONS'
	usage.
	* gcc.target/arm/cmse/cmse.exp: Likewise.
	* gcc.target/arm/pure-code/pure-code.exp: Likewise.
