[PATCH 2/2] ld, gas: run the AArch64 PE tests for aarch64-pc-cygwin

[Dennis Ameling]

Several AArch64 PE tests are gated on aarch64-*-pe* and aarch64-*-mingw*,
or on *-*-mingw* and *-*-pe*, so they are skipped entirely for
aarch64-pc-cygwin even though the target uses the same aarch64pe emulation
and the same object format.

Add the target to those gates.  This runs existing coverage rather than
adding new tests: the image base, .secrel32 and .secidx link tests, the
PDB tests, which this target supports, the gas PE and SEH tests, and the
CodeView tests, CodeView being a PE debug format that the PDB support
consumes.

pe-aarch64 in ld is deliberately left out.  It matches absolute addresses
and so is specific to the 0x140000000 image base, whereas Cygwin targets
set move_default_addr_high and default to 0x100400000.  That is long
standing Cygwin behaviour rather than anything specific to AArch64, so the
gate for that one test is split out rather than the test being changed.
